Likewise, Druid [Segments](Segments.html) are partitioned to contain data for some interval of time and segments are distributed across a cluster. Consider a simple datasource with 7 segments where each segment contains data for a given day of the week.

Zookeeper maintains information about [Compute](Compute.html) and [Realtime](Realtime.html) nodes and the segments they are serving. For every datasource in Zookeeper, the Broker node builds a timeline of segments and the nodes that serve them. When queries are received for a specific datasource and interval, the Broker node performs a lookup into the timeline associated with the query datasource for the query interval and retrieves the nodes that contain data for the query.

Each time a broker node receives a query, it first maps the query to a set of segments. A subset of these segment results may already exist in the cache and the results can be directly pulled from the cache. For any segment results that do not exist in the cache, the broker node will forward the query to the +compute nodes. Once the compute nodes return their results, the broker will store those results in the cache.

The upper limit of effectively utilized cores is not well characterized yet and would depend on types of queries, query load, and the schema. Compute daemons should have a heap a size of at least 1GB per core for normal usage, but could be squeezed into a smaller heap for testing. Since in-memory caching is essential for good performance, even more RAM is better. Broker nodes will use RAM for caching, so they do more than just route queries. + +The effective utilization of cores by Zookeeper, MySQL, and Master nodes is likely to be between 1 and 2 for each process/daemon, so these could potentially share a machine with lots of cores.

If your data center is suitably provisioned for networked storage, perhaps with separate LAN/NICs just for storage, then mounted might work fine. + +Setup +----- + +Setting up a cluster is essentially just firing up all of the nodes you want with the proper [configuration](configuration.html).

The master will only assign segments to a “historical” node and the broker has some intelligence around its ability to cache results when talking to a realtime node. This does not need to be set for the master or the broker. + +`druid.host` should be set to the hostname and port that can be used to talk to the given server process. Basically, someone should be able to send a request to http://\${druid.host}/ and actually talk to the process. + +`druid.port` should be set to the port that the server should listen on. In the vast majority of cases, this port should be the same as what is on `druid.host`. + +Build/Run +--------- + +The simplest way to build and run from the repository is to run `mvn package` from the base directory and then take `druid-services/target/druid-services-*-selfcontained.jar` and push that around to your machines; the jar does not need to be expanded, and since it contains the main() methods for each kind of service, it is **not** invoked with java ~~jar.

It was designed with the intent of being a service and maintaining 100% uptime in the face of code deployments, machine failures and other eventualities of a production system. It can be useful for back-office use cases as well, but design decisions were made explicitly targetting an always-up service. + +Druid currently allows for single-table queries in a similar manner to [Dremel](http://research.google.com/pubs/pub36632.html) and [PowerDrill](http://www.vldb.org/pvldb/vol5/p1436_alexanderhall_vldb2012.pdf). It adds to the mix + +1. columnar storage format for partially nested data structures +2. hierarchical query distribution with intermediate pruning +3. indexing for quick filtering +4. realtime ingestion (ingested data is immediately available for querying) +5. fault-tolerant distributed architecture that doesn’t lose data + +As far as a comparison of systems is concerned, Druid sits in between PowerDrill and Dremel on the spectrum of functionality. It implements almost everything Dremel offers (Dremel handles arbitrary nested data structures while Druid only allows for a single level of array-based nesting) and gets into some of the interesting data layout and compression methods from PowerDrill. + +Druid is a good fit for products that require real-time data ingestion of a single, large data stream. Especially if you are targetting no-downtime operation and are building your product on top of a time-oriented summarization of the incoming data stream. Druid is probably not the right solution if you care more about query flexibility and raw data access than query speed and no-downtime operation. When talking about query speed it is important to clarify what “fast” means, with Druid it is entirely within the realm of possibility (we have done it) to achieve queries that run in single-digit seconds across a 6TB data set. + +### Architecture + +Druid is architected as a grouping of systems each with a distinct role and together they form a working system. The name comes from the Druid class in many role-playing games: it is a shape-shifter, capable of taking many different forms to fulfill various different roles in a group. + +The node types that currently exist are: +\* **Compute** nodes are the workhorses that handle storage and querying on “historical” data (non-realtime) +\* **Realtime** nodes ingest data in real-time, they are in charge of listening to a stream of incoming data and making it available immediately inside the Druid system. As data they have ingested ages, they hand it off to the compute nodes. +\* **Master** nodes act as coordinators. They look over the grouping of computes and make sure that data is available, replicated and in a generally “optimal” configuration. +\* **Broker** nodes understand the topology of data across all of the other nodes in the cluster and re-write and route queries accordingly +\* **Indexer** nodes form a cluster of workers to load batch and real-time data into the system as well as allow for alterations to the data stored in the system (also known as the Indexing Service) + +This separation allows each node to only care about what it is best at. By separating Compute and Realtime, we separate the memory concerns of listening on a real-time stream of data and processing it for entry into the system. By separating the Master and Broker, we separate the needs for querying from the needs for maintaining “good” data distribution across the cluster. + +All nodes can be run in some highly available fashion. Either as symmetric peers in a share-nothing cluster or as hot-swap failover nodes. + +Aside from these nodes, there are 3 external dependencies to the system: + +1. A running [ZooKeeper](http://zookeeper.apache.org/) cluster for cluster service discovery and maintenance of current data topology +2. A MySQL instance for maintenance of metadata about the data segments that should be served by the system +3. A “deep storage” LOB store/file system to hold the stored segments + +### Data Storage + +Getting data into the Druid system requires an indexing process. This gives the system a chance to analyze the data, add indexing structures, compress and adjust the layout in an attempt to optimize query speed. A quick list of what happens to the data follows. + +- Converted to columnar format +- Indexed with bitmap indexes +- Compressed using various algorithms + - LZF (switching to Snappy is on the roadmap, not yet implemented) + - Dictionary encoding w/ id storage minimization + - Bitmap compression + - RLE (on the roadmap, but not yet implemented) + +The output of the indexing process is stored in a “deep storage” LOB store/file system ([Deep Storage](Deep Storage.html) for information about potential options). Data is then loaded by compute nodes by first downloading the data to their local disk and then memory mapping it before serving queries. + +If a compute node dies, it will no longer serve its segments, but given that the segments are still available on the “deep storage” any other node can simply download the segment and start serving it. This means that it is possible to actually remove all compute nodes from the cluster and then re-provision them without any data loss. It also means that if the “deep storage” is not available, the nodes can continue to serve the segments they have already pulled down (i.e. the cluster goes stale, not down). + +In order for a segment to exist inside of the cluster, an entry has to be added to a table in a MySQL instance. This entry is a self-describing bit of metadata about the segment, it includes things like the schema of the segment, the size, and the location on deep storage. These entries are what the Master uses to know what data **should** be available on the cluster. + +### Fault Tolerance + +- **Compute** As discussed above, if a compute node dies, another compute node can take its place and there is no fear of data loss +- **Master** Can be run in a hot fail-over configuration. If no masters are running, then changes to the data topology will stop happening (no new data and no data balancing decisions), but the system will continue to run. +- **Broker** Can be run in parallel or in hot fail-over. +- **Realtime** Depending on the semantics of the delivery stream, multiple of these can be run in parallel processing the exact same stream. They periodically checkpoint to disk and eventually push out to the Computes. Steps are taken to be able to recover from process death, but loss of access to the local disk can result in data loss if this is the only method of adding data to the system. +- **“deep storage” file system** If this is not available, new data will not be able to enter the cluster, but the cluster will continue operating as is. +- **MySQL** If this is not available, the master will be unable to find out about new segments in the system, but it will continue with its current view of the segments that should exist in the cluster. +- **ZooKeeper** If this is not available, data topology changes will not be able to be made, but the Brokers will maintain their most recent view of the data topology and continue serving requests accordingly. + +### Query processing + +A query first enters the Broker, where the broker will match the query with the data segments that are known to exist. It will then pick a set of machines that are serving those segments and rewrite the query for each server to specify the segment(s) targetted. The Compute/Realtime nodes will take in the query, process them and return results. The Broker then takes the results and merges them together to get the final answer, which it returns. In this way, the broker can prune all of the data that doesn’t match a query before ever even looking at a single row of data. + +For filters at a more granular level than what the Broker can prune based on, the indexing structures inside each segment allows the compute nodes to figure out which (if any) rows match the filter set before looking at any row of data. It can do all of the boolean algebra of the filter on the bitmap indices and never actually look directly at a row of data. + +Once it knows the rows that match the current query, it can access the columns it cares about for those rows directly without having to load data that it is just going to throw away. + +The following diagram shows the data flow for queries without showing batch indexing: + +![Simple Data Flow](https://raw.github.com/metamx/druid/master/doc/data_flow_simple.png "Simple Data Flow") + +### In-memory? + +Druid is not always and only in-memory. When we first built it, it is true that it was all in-memory all the time, but as time went on the price-performance tradeoff ended up swinging towards keeping all of our customers data in memory all the time a non-starter. We then added the ability to memory map data and allow the OS to handle paging data in and out of memory on demand. Our production cluster is primarily configured to operate with this memory mapping behavior and we are definitely over-subscribed in terms of memory available vs. data a node is serving. + +As you read some of the old blog posts or other literature about the project, you will see “in-memory” often touted as that is the history of where Druid came from, but the technical reality is that there is a spectrum of price vs. performance and being able to slide along it from all in-memory (high cost, great performance) to mostly on disk (low cost, low performance) is the important knob to be able to adjust. diff --git a/docs/Download.md b/docs/Download.md new file mode 100644 index 000000000000..1bf1352de58c --- /dev/null +++ b/docs/Download.md @@ -0,0 +1,14 @@ +--- +layout: default +--- +A version may be declared as a release candidate if it has been deployed to a sizable production cluster.

Writes are always supported but updates to data may take some time before all replicas sync up (data reconciliation is done at read time).

This means that for the data to exist in the Druid cluster, it must exist as a local copy on a historical node. If deep storage becomes unavailable for any reason, new segments will not be loaded into the system, but the cluster will continue to operate exactly as it was when the backing store disappeared. + +Impala and Shark, on the other hand, pull their data in from HDFS (or some other Hadoop FileSystem) in response to a query. This has implications for the operation of queries if you need to take HDFS down for a bit (say a software upgrade). It's possible that data that has been cached in the nodes is still available when the backing file system goes down, but I'm not sure. + +This is just one example, but Druid was built to continue operating in the face of failures of any one of its various pieces. The [Design](Design.html) describes these design decisions from the Druid side in more detail. + +## Query Speed + +Druid takes control of the data given to it, storing it in a column-oriented fashion, compressing it and adding indexing structures. All of which add to the speed at which queries can be processed. The column orientation means that we only look at the data that a query asks for in order to compute the answer. Compression increases the data storage capacity of RAM and allows us to fit more data into quickly accessible RAM. Indexing structures mean that as you add boolean filters to your queries, we do less processing and you get your result faster, whereas a lot of processing engines do *more* processing when filters are added. + +Impala/Shark can basically be thought of as daemon caching layers on top of HDFS. They are processes that stay on even if there is no query running (eliminating the JVM startup costs from Hadoop MapReduce) and they have facilities to cache data locally so that it can be accessed and updated quicker. But, I do not believe they go beyond caching capabilities to actually speed up queries. So, at the end of the day, they don't change the paradigm from a brute-force, scan-everything query processing paradigm. + +## Data Ingestion + +Druid is built to allow for real-time ingestion of data. You can ingest data and query it immediately upon ingestion, the latency between how quickly the event is reflected in the data is dominated by how long it takes to deliver the event to Druid. + +Impala/Shark, being based on data in HDFS or some other backing store, are limited in their data ingestion rates by the rate at which that backing store can make data available. Generally, the backing store is the biggest bottleneck for how quickly data can become available. + +## Query Flexibility + +Druid supports timeseries and groupBy style queries.

Druid provides for cost effective, always-on, realtime data ingestion and arbitrary data exploration. + +- Check out some [Examples](Examples.html) +- Try out Druid with our Getting Started [Tutorial](https://github.com/metamx/druid/wiki/Tutorial%3A-A-First-Look-at-Druid) +- Learn more by reading the [White Paper](http://static.druid.io/docs/druid.pdf) + +Why Druid? +---------- + +Druid was originally created to resolve query latency issues seen with trying to use Hadoop to power an interactive service. Hadoop has shown the world that it’s possible to house your data warehouse on commodity hardware for a fraction of the price of typical solutions. As people adopt Hadoop for their data warehousing needs, they find two things. + +1. They can now query all of their data in a fairly flexible manner and answer any question they have +2. The queries take a long time + +The first one is the joy that everyone feels the first time they get Hadoop running. The latter is what they realize after they have used Hadoop interactively for a while because Hadoop is optimized for throughput, not latency. Druid is a system that you can set up in your organization next to Hadoop. It provides the ability to access your data in an interactive slice-and-dice fashion. It trades off some query flexibility and takes over the storage format in order to provide the speed. + +Druid is especially useful if you are summarizing your data sets and then querying the summarizations. If you put your summarizations into Druid, you will get quick queryability out of a system that you can be confident will scale up as your data volumes increase. Deployments have scaled up to 2TB of data per hour at peak ingested and aggregated in real-time. + +We have more details about the general design of the system and why you might want to use it in our [White Paper](http://static.druid.io/docs/druid.pdf) or in our [Design](Design.html) doc. + +The data store world is vast, confusing and constantly in flux. This page is meant to help potential evaluators decide whether Druid is a good fit for the problem one needs to solve. If anything about it is incorrect please provide that feedback on the mailing list or via some other means, we will fix this page. + +#### When Druid? +\* You need to do interactive, fast, exploration of large amounts of data +\* You need analytics (not key value store) +\* You have a lot of data (10s of Billions of events added per day, 10s of TB of data added per day) +\* You want to do your analysis on data as it’s happening (realtime) +\* Your store needs to be always-on, 24x7x365 and years into the future. + +#### Not Druid? +\* The amount of data you have can easily be handled by MySql +\* Your querying for individual entries or doing lookups (Not Analytics) +\* Batch is good enough +\* Canned queries is good enough +\* Downtime is no big deal + +#### Druid vs… +\* [Druid-vs-Impala-or-Shark](Druid-vs-Impala-or-Shark.html) +\* [Druid-vs-Redshift](Druid-vs-Redshift.html) +\* [Druid-vs-Vertica](Druid-vs-Vertica.html) +\* [Druid-vs-Cassandra](Druid-vs-Cassandra.html) +\* [Druid-vs-Hadoop](Druid-vs-Hadoop.html) + +Key Features +------------ + +- **Designed for Analytics** - Druid is built for exploratory analytics for OLAP workflows (streamalytics). It supports a variety of filters, aggregators and query types and provides a framework for plugging in new functionality. Users have leveraged Druid’s infrastructure to develop features such as top K queries and histograms. +- **Interactive Queries** - Druid’s low latency data ingestion architecture allows events to be queried milliseconds after they are created. Druid’s query latency is optimized by only reading and scanning exactly what is needed. Aggregate and filter on data without sitting around waiting for results. +- **Highly Available** - Druid is used to back SaaS implementations that need to be up all the time. Your data is still available and queryable during system updates. Scale up or down without data loss. +- **Scalable** - Existing Druid deployments handle billions of events and terabytes of data per day.

We will announce when we feel the indexing service and the configurations described are stable. + +The indexing service is a distributed task/job queue. It accepts requests in the form of [Tasks](Tasks.html) and executes those tasks across a set of worker nodes. Worker capacity can be automatically adjusted based on the number of tasks pending in the system. The indexing service is highly available, has built in retry logic, and can backup per task logs in deep storage. + +The indexing service is composed of two main components, a coordinator node that manages task distribution and worker capacity, and worker nodes that execute tasks in separate JVMs. + +Preamble +-------- + +The truth is, the indexing service is an experience that is difficult to characterize with words. When they asked me to write this preamble, I was taken aback. I wasn’t quite sure what exactly to write or how to describe this… entity. I accepted the job, as much for the challenge and inner growth as the money, and took to the mountains for reflection. Six months later, I knew I had it, I was done and had achieved the next euphoric victory in the continuous struggle that plagues my life. But, enough about me. This is about the indexing service. + +The indexing service is philosophical transcendence, an infallible truth that will shape your soul, mold your character, and define your reality. The indexing service is creating world peace, playing with puppies, unwrapping presents on Christmas morning, cradling a loved one, and beating Goro in Mortal Kombat for the first time. The indexing service is sustainable economic growth, global propensity, and a world of transparent financial transactions. The indexing service is a true belieber. The indexing service is panicking because you forgot you signed up for a course and the big exam is in a few minutes, only to wake up and realize it was all a dream. What is the indexing service? More like what isn’t the indexing service. The indexing service is here and it is ready, but are you? + +Indexer Coordinator Node +------------------------ + +The indexer coordinator node exposes HTTP endpoints where tasks can be submitted by posting a JSON blob to specific endpoints. It can be started by launching IndexerCoordinatorMain.java. The indexer coordinator node can operate in local mode or remote mode. In local mode, the coordinator and worker run on the same host and port. In remote mode, worker processes run on separate hosts and ports. + +Tasks can be submitted via POST requests to: + + http://:/druid/indexer/v1/task + +Tasks can cancelled via POST requests to: + + http://:/druid/indexer/v1/task/{taskId}/shutdown + +Issuing the cancel request once sends a graceful shutdown request. Graceful shutdowns may not stop a task right away, but instead issue a safe stop command at a point deemed least impactful to the system. Issuing the cancel request twice in succession will kill –9 the task. + +Task statuses can be retrieved via GET requests to: + + http://:/druid/indexer/v1/task/{taskId}/status + +Task segments can be retrieved via GET requests to: + + http://:/druid/indexer/v1/task/{taskId}/segments + +When a task is submitted, the coordinator creates a lock over the data source and interval of the task. The coordinator also stores the task in a MySQL database table. The database table is read at startup time to bootstrap any tasks that may have been submitted to the coordinator but may not yet have been executed. + +The coordinator also exposes a simple UI to show what tasks are currently running on what nodes at + + http://:/static/console.html + +#### Task Execution + +The coordinator retrieves worker setup metadata from the Druid [MySQL](MySQL.html) config table. This metadata contains information about the version of workers to create, the maximum and minimum number of workers in the cluster at one time, and additional information required to automatically create workers. + +Tasks are assigned to workers by creating entries under specific /tasks paths associated with a worker, similar to how the Druid master node assigns segments to compute nodes. See [Worker Configuration](Indexing-Service#configuration-1). Once a worker picks up a task, it deletes the task entry and announces a task status under a /status path associated with the worker. Tasks are submitted to a worker until the worker hits capacity. If all workers in a cluster are at capacity, the indexer coordinator node automatically creates new worker resources. + +#### Autoscaling + +The Autoscaling mechanisms currently in place are tightly coupled with our deployment infrastructure but the framework should be in place for other implementations. We are highly open to new implementations or extensions of the existing mechanisms. In our own deployments, worker nodes are Amazon AWS EC2 nodes and they are provisioned to register themselves in a [galaxy](https://github.com/ning/galaxy) environment. + +The Coordinator node controls the number of workers in the cluster according to a worker setup spec that is submitted via a POST request to the indexer at: + + http://:/druid/indexer/v1/worker/setup + +A sample worker setup spec is shown below: + + { + "minVersion":"some_version", + "minNumWorkers":"0", + "maxNumWorkers":"10", + "nodeData": { + "type":"ec2", + "amiId":"ami-someId", + "instanceType":"m1.xlarge", + "minInstances":"1", + "maxInstances":"1", + "securityGroupIds":["securityGroupIds"], + "keyName":"keyName" + }, + "userData":{ + "classType":"galaxy", + "env":"druid", + "version":"druid_version", + "type":"sample_cluster/worker" + } + } + + +Issuing a GET request at the same URL will return the current worker setup spec that is currently in place.

More specifically, the Druid master node communicates to compute nodes to load or drop segments based on configurations. The Druid master is responsible for loading new segments, dropping outdated segments, managing segment replication, and balancing segment load. + +The Druid master runs periodically and the time between each run is a configurable parameter. Each time the Druid master runs, it assesses the current state of the cluster before deciding on the appropriate actions to take. Similar to the broker and compute nodes, the Druid master maintains a connection to a Zookeeper cluster for current cluster information. The master also maintains a connection to a database containing information about available segments and rules. Available segments are stored in a segment table and list all segments that should be loaded in the cluster. Rules are stored in a rule table and indicate how segments should be handled. + +Before any unassigned segments are serviced by compute nodes, the available compute nodes for each tier are first sorted in terms of capacity, with least capacity servers having the highest priority. Unassigned segments are always assigned to the nodes with least capacity to maintain a level of balance between nodes. The master does not directly communicate with a compute node when assigning it a new segment; instead the master creates some temporary information about the new segment under load queue path of the compute node. Once this request is seen, the compute node will load the segment and begin servicing it. + +Rules +----- + +Segments are loaded and dropped from the cluster based on a set of rules. Rules indicate how segments should be assigned to different compute node tiers and how many replicants of a segment should exist in each tier. Rules may also indicate when segments should be dropped entirely from the cluster. The master loads a set of rules from the database. Rules may be specific to a certain datasource and/or a default set of rules can be configured. Rules are read in order and hence the ordering of rules is important. The master will cycle through all available segments and match each segment with the first rule that applies. Each segment may only match a single rule + +For more information on rules, see [Rule Configuration](Rule-Configuration.html). + +Cleaning Up Segments +-------------------- + +Each run, the Druid master compares the list of available database segments in the database with the current segments in the cluster. Segments that are not in the database but are still being served in the cluster are flagged and appended to a removal list. Segments that are overshadowed (their versions are too old and their data has been replaced by newer segments) are also dropped. + +Segment Availability +-------------------- + +If a compute node restarts or becomes unavailable for any reason, the Druid master will notice a node has gone missing and treat all segments served by that node as being dropped. Given a sufficient period of time, the segments may be reassigned to other compute nodes in the cluster. However, each segment that is dropped is not immediately forgotten. Instead, there is a transitional data structure that stores all dropped segments with an associated lifetime. The lifetime represents a period of time in which the master will not reassign a dropped segment. Hence, if a compute node becomes unavailable and available again within a short period of time, the compute node will start up and serve segments from its cache without any those segments being reassigned across the cluster. + +Balancing Segment Load +---------------------- + +To ensure an even distribution of segments across compute nodes in the cluster, the master node will find the total size of all segments being served by every compute node each time the master runs. For every compute node tier in the cluster, the master node will determine the compute node with the highest utilization and the compute node with the lowest utilization. The percent difference in utilization between the two nodes is computed, and if the result exceeds a certain threshold, a number of segments will be moved from the highest utilized node to the lowest utilized node. There is a configurable limit on the number of segments that can be moved from one node to another each time the master runs. Segments to be moved are selected at random and only moved if the resulting utilization calculation indicates the percentage difference between the highest and lowest servers has decreased. + +HTTP Endpoints +-------------- + +The master node exposes several HTTP endpoints for interactions. + +### GET + +/info/master - returns the current true master of the cluster as a JSON object.

Segment information can be displayed in raw JSON form or as part of a sortable and filterable table. + +The master console also exposes an interface to creating and editing rules. All valid datasources configured in the segment database, along with a default datasource, are available for configuration. Rules of different types can be added, deleted or edited. + +FAQ +--- + +1. **Do clients ever contact the master node?** + +The master is not involved in the lifecycle of a query. + +Compute nodes never directly contact the master node. The Druid master tells the compute nodes to load/drop data via Zookeeper, but the compute nodes are completely unaware of the master. + +Brokers also never contact the master. Brokers base their understanding of the data topology on metadata exposed by the compute nodes via ZK and are completely unaware of the master. + +2. **Does it matter if the master node starts up before or after other processes?** + +No. If the Druid master is not started up, no new segments will be loaded in the cluster and outdated segments will not be dropped. However, the master node can be started up at any time, and after a configurable delay, will start running master tasks. + +This also means that if you have a working cluster and all of your masters die, the cluster will continue to function, it just won’t experience any changes to its data topology. + +Running +------- + +Master nodes can be run using the `com.metamx.druid.http.MasterMain` class. + +Configuration +------------- + +See [Configuration](Configuration.html). diff --git a/docs/MySQL.md b/docs/MySQL.md new file mode 100644 index 000000000000..713ad0ab18d5 --- /dev/null +++ b/docs/MySQL.md @@ -0,0 +1,47 @@ +--- +layout: default +--- +MySQL is an external dependency of Druid.

We scrape IRC channels for several different languages and load this data into Druid. + +Each event has a timestamp indicating the time of the edit (in UTC time), a list of dimensions indicating various metadata about the event (such as information about the user editing the page and where the user resides), and a list of metrics associated with the event (such as the number of characters added and deleted). + +Specifically. the data schema looks like so: + +Dimensions (things to filter on): +\`\`\`json +“page” +“language” +“user” +“unpatrolled” +“newPage” +“robot” +“anonymous” +“namespace” +“continent” +“country” +“region” +“city” +\`\`\` + +Metrics (things to aggregate over): +\`\`\`json +“count” +“added” +“delta” +“deleted” +\`\`\` + +These metrics track the number of characters added, deleted, and changed. + +Setting Up +---------- + +There are two ways to setup Druid: download a tarball, or [Build From Source](Build From Source.html). You only need to do one of these. + +### Download a Tarball + +We’ve built a tarball that contains everything you’ll need. You’ll find it [here](http://static.druid.io/artifacts/releases/druid-services-0.5.54-bin.tar.gz) +Download this file to a directory of your choosing. + +You can extract the awesomeness within by issuing: + + tar -zxvf druid-services-*-bin.tar.gz + +Not too lost so far right? That’s great! If you cd into the directory: + + cd druid-services-0.5.54 + +You should see a bunch of files: +\* run\_example\_server.sh +\* run\_example\_client.sh +\* LICENSE, config, examples, lib directories + +Running Example Scripts +----------------------- + +Let’s start doing stuff. You can start a Druid [Realtime](Realtime.html) node by issuing: + + ./run_example_server.sh + +Select “wikipedia”. + +Once the node starts up you will see a bunch of logs about setting up properties and connecting to the data source. If everything was successful, you should see messages of the form shown below. + + + 2013-07-19 21:54:05,154 INFO [main] com.metamx.druid.realtime.RealtimeNode - Starting Jetty + 2013-07-19 21:54:05,154 INFO [main] org.mortbay.log - jetty-6.1.x + 2013-07-19 21:54:05,171 INFO [chief-wikipedia] com.metamx.druid.realtime.plumber.RealtimePlumberSchool - Expect to run at [2013-07-19T22:03:00.000Z] + 2013-07-19 21:54:05,246 INFO [main] org.mortbay.log - Started SelectChannelConnector@0.0.0.0:8083 + + +The Druid real time-node ingests events in an in-memory buffer. Periodically, these events will be persisted to disk. If you are interested in the details of our real-time architecture and why we persist indexes to disk, I suggest you read our [White Paper](http://static.druid.io/docs/druid.pdf). + +Okay, things are about to get real(~~time). To query the real-time node you’ve spun up, you can issue: +\./run\_example\_client.sh\ +Select “wikipedia” once again. This script issues ]s to the data we’ve been ingesting. The query looks like this: +\`\`\`json +{ + [queryType]("groupBy"), + [dataSource]("wikipedia"), + [granularity]("minute"), + [dimensions]([) + “page” + ], + [aggregations]([) + { + [type]("count"), + [name]("rows") + }, + { + [type]("longSum"), + [fieldName]("edit_count"), + [name]("count") + } + ], + [filter]({) + [type]("selector"), + [dimension]("namespace"), + [value]("article") + }, + [intervals]([) + “2013-06-01T00:00/2020-01-01T00” + ] +} +\`\`\` +This is a **groupBy** query, which you may be familiar with from SQL. We are grouping, or aggregating, via the **dimensions** field: . We are **filtering** via the **“namespace”** dimension, to only look at edits on **“articles”**. Our **aggregations** are what we are calculating: a count of the number of data rows, and a count of the number of edits that have occurred. +The result looks something like this: +\`\`\`json +[ + { + [version]() “v1”, + [timestamp]() “2013-09-04T21:44:00.000Z”, + [event]() { + [count]() 0, + [page]() “2013\\u201314\_Brentford\_F.C.*season", + [rows]() 1 + } + }, + { + [version]() "v1", + [timestamp]() "2013-09-04T21:44:00.000Z", + [event]() { + [count]() 0, + [page]() "8e*00e9tape\_du\_Tour\_de\_France\_2013”, + [rows]() 1 + } + }, + { + [version]() “v1”, + [timestamp]() “2013-09-04T21:44:00.000Z”, + [event]() { + [count]() 0, + [page]() “Agenda\_of\_the\_Tea\_Party\_movement”, + [rows]() 1 + } + }, +… +\`\`\` +This groupBy query is a bit complicated and we’ll return to it later. For the time being, just make sure you are getting some blocks of data back. If you are having problems, make sure you have [curl](http://curl.haxx.se/) installed. Control+C to break out of the client script. +h2. Querying Druid +In your favorite editor, create the file: +\time\_boundary\_query.body\ +Druid queries are JSON blobs which are relatively painless to create programmatically, but an absolute pain to write by hand. So anyway, we are going to create a Druid query by hand. Add the following to the file you just created: +\ +{ + [queryType]() “timeBoundary”, + [dataSource]() “wikipedia” +} +\ +The ] is one of the simplest Druid queries. To run the query, you can issue: +\ curl~~X POST ‘http://localhost:8083/druid/v2/?pretty’ ~~H ‘content-type: application/json’~~d ```` time_boundary_query.body + +We get something like this JSON back: + +```json +[ { + "timestamp" : "2013-09-04T21:44:00.000Z", + "result" : { + "minTime" : "2013-09-04T21:44:00.000Z", + "maxTime" : "2013-09-04T21:47:00.000Z" + } +} ] +``` +As you can probably tell, the result is indicating the maximum and minimum timestamps we've seen thus far (summarized to a minutely granularity). Let's explore a bit further. + +Return to your favorite editor and create the file: +
timeseries_query.body
+ +We are going to make a slightly more complicated query, the [TimeseriesQuery](TimeseriesQuery.html). Copy and paste the following into the file: +

+{
+    "queryType": "timeseries", 
+    "dataSource": "wikipedia", 
+    "intervals": [
+        "2010-01-01/2020-01-01"
+    ], 
+    "granularity": "all", 
+    "aggregations": [
+        {
+            "type": "longSum", 
+            "fieldName": "count",
+            "name": "edit_count"
+        }, 
+        {
+            "type": "doubleSum", 
+            "fieldName": "added", 
+            "name": "chars_added"
+        }
+    ]
+}
+
+ +You are probably wondering, what are these [Granularities](Granularities.html) and [Aggregations](Aggregations.html) things? What the query is doing is aggregating some metrics over some span of time. +To issue the query and get some results, run the following in your command line: +
curl -X POST 'http://localhost:8083/druid/v2/?pretty' -H 'content-type: application/json'  -d  ````timeseries\_query.body
+
+
+Once again, you should get a JSON blob of text back with your results, that looks something like this: + +\`\`\`json +[ { + “timestamp” : “2013-09-04T21:44:00.000Z”, + “result” : { + “chars\_added” : 312670.0, + “edit\_count” : 733 + } +} ] +\`\`\` + +If you issue the query again, you should notice your results updating. + +Right now all the results you are getting back are being aggregated into a single timestamp bucket. What if we wanted to see our aggregations on a per minute basis? What field can we change in the query to accomplish this? + +If you loudly exclaimed “we can change granularity to minute”, you are absolutely correct! We can specify different granularities to bucket our results, like so: + + + { + "queryType": "timeseries", + "dataSource": "wikipedia", + "intervals": [ + "2010-01-01/2020-01-01" + ], + "granularity": "minute", + "aggregations": [ + { + "type": "longSum", + "fieldName": "count", + "name": "edit_count" + }, + { + "type": "doubleSum", + "fieldName": "added", + "name": "chars_added" + } + ] + } + + +This gives us something like the following: + +\`\`\`json +[ + { + “timestamp” : “2013-09-04T21:44:00.000Z”, + “result” : { + “chars\_added” : 30665.0, + “edit\_count” : 128 + } + }, { + “timestamp” : “2013-09-04T21:45:00.000Z”, + “result” : { + “chars\_added” : 122637.0, + “edit\_count” : 167 + } + }, { + “timestamp” : “2013-09-04T21:46:00.000Z”, + “result” : { + “chars\_added” : 78938.0, + “edit\_count” : 159 + } + }, +… +\`\`\` + +Solving a Problem +----------------- + +One of Druid’s main powers is to provide answers to problems, so let’s pose a problem. What if we wanted to know what the top pages in the US are, ordered by the number of edits over the last few minutes you’ve been going through this tutorial? To solve this problem, we have to return to the query we introduced at the very beginning of this tutorial, the [GroupByQuery](GroupByQuery.html). It would be nice if we could group by results by dimension value and somehow sort those results… and it turns out we can! + +Let’s create the file: + + group_by_query.body + and put the following in there: + 

+    {
+        "queryType": "groupBy", 
+        "dataSource": "wikipedia", 
+        "granularity": "all", 
+        "dimensions": [
+            "page"
+        ], 
+        "orderBy": {
+            "type": "default", 
+            "columns": [
+                {
+                    "dimension": "edit_count", 
+                    "direction": "DESCENDING"
+                }
+            ], 
+            "limit": 10
+        }, 
+        "aggregations": [
+            {
+                "type": "longSum", 
+                "fieldName": "count", 
+                "name": "edit_count"
+            }
+        ], 
+        "filter": {
+            "type": "selector", 
+            "dimension": "country", 
+            "value": "United States"
+        }, 
+        "intervals": [
+            "2012-10-01T00:00/2020-01-01T00"
+        ]
+    }
+    
+
+Woah! Our query just got a way more complicated. Now we have these [Filters](Filters.html) things and this [OrderBy](OrderBy.html) thing. Fear not, it turns out the new objects we’ve introduced to our query can help define the format of our results and provide an answer to our question.
+
+If you issue the query:
+
+    curl -X POST 'http://localhost:8083/druid/v2/?pretty' -H 'content-type: application/json'  -d @group_by_query.body
+
+You should see an answer to our question. As an example, some results are shown below:
+
+\`\`\`json
+[
+ {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “page” : “RTC\_Transit”,
+ “edit\_count” : 6
+ }
+ }, {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “page” : “List\_of\_Deadly\_Women\_episodes”,
+ “edit\_count” : 4
+ }
+ }, {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “page” : “User\_talk:David\_Biddulph”,
+ “edit\_count” : 4
+ }
+ },
+…
+\`\`\`
+
+Feel free to tweak other query parameters to answer other questions you may have about the data.

+Welcome back! In our first [tutorial](https://github.com/metamx/druid/wiki/Tutorial%3A-A-First-Look-at-Druid), we introduced you to the most basic Druid setup: a single realtime node. We streamed in some data and queried it. Realtime nodes collect very recent data and periodically hand that data off to the rest of the Druid cluster. Some questions about the architecture must naturally come to mind. What does the rest of Druid cluster look like? How does Druid load available static data?
+
+This tutorial will hopefully answer these questions!
+
+In this tutorial, we will set up other types of Druid nodes as well as and external dependencies for a fully functional Druid cluster. The architecture of Druid is very much like the [Megazord](http://www.youtube.com/watch?v=7mQuHh1X4H4) from the popular 90s show Mighty Morphin' Power Rangers. Each Druid node has a specific purpose and the nodes come together to form a fully functional system.
+
+## Downloading Druid ##
+
+If you followed the first tutorial, you should already have Druid downloaded. If not, let's go back and do that first.
+
+You can download the latest version of druid [here](http://static.druid.io/artifacts/releases/druid-services-0.5.54-bin.tar.gz)
+
+and untar the contents within by issuing:
+```bash
+tar -zxvf druid-services-*-bin.tar.gz
+cd druid-services-*
+```
+
+You can also [Build From Source](Build-From-Source.html).
+
+## External Dependencies ##
+
+Druid requires 3 external dependencies. A "deep" storage that acts as a backup data repository, a relational database such as MySQL to hold configuration and metadata information, and [Apache Zookeeper](http://zookeeper.apache.org/) for coordination among different pieces of the cluster.
+
+For deep storage, we have made a public S3 bucket (static.druid.io) available where data for this particular tutorial can be downloaded. More on the data [later](https://github.com/metamx/druid/wiki/Tutorial-Part-2#the-data).
+
+### Setting up MySQL ###
+
+1. If you don't already have it, download MySQL Community Server here: [http://dev.mysql.com/downloads/mysql/](http://dev.mysql.com/downloads/mysql/)
+2. Install MySQL
+3. Create a druid user and database
+```bash
+mysql -u root
+```
+```sql
+GRANT ALL ON druid.* TO 'druid'@'localhost' IDENTIFIED BY 'diurd';
+CREATE database druid;
+```
+
+### Setting up Zookeeper ###
+```bash
+curl http://www.motorlogy.com/apache/zookeeper/zookeeper-3.4.5/zookeeper-3.4.5.tar.gz -o zookeeper-3.4.5.tar.gz
+tar xzf zookeeper-3.4.5.tar.gz
+cd zookeeper-3.4.5
+cp conf/zoo_sample.cfg conf/zoo.cfg
+./bin/zkServer.sh start
+cd ..
+```
+
+## The Data ##
+
+Similar to the first tutorial, the data we will be loading is based on edits that have occurred on Wikipedia. Every time someone edits a page in Wikipedia, metadata is generated about the editor and edited page. Druid collects each individual event and packages them together in a container known as a [segment](https://github.com/metamx/druid/wiki/Segments). Segments contain data over some span of time. We've prebuilt a segment for this tutorial and will cover making your own segments in other [pages](https://github.com/metamx/druid/wiki/Loading-Your-Data).The segment we are going to work with has the following format:
+
+Dimensions (things to filter on):
+```json
+"page"
+"language"
+"user"
+"unpatrolled"
+"newPage"
+"robot"
+"anonymous"
+"namespace"
+"continent"
+"country"
+"region"
+"city"
+```
+
+Metrics (things to aggregate over):
+```json
+"count"
+"added"
+"delta"
+"deleted"
+```
+
+## The Cluster ##
+
+Let's start up a few nodes and download our data. First things though, let's create a config directory where we will store configs for our various nodes:
+
+```
+mkdir config
+```
+
+If you are interested in learning more about Druid configuration files, check out this [link](https://github.com/metamx/druid/wiki/Configuration). Many aspects of Druid are customizable. For the purposes of this tutorial, we are going to use default values for most things.
+
+### Start a Master Node ###
+
+Master nodes are in charge of load assignment and distribution. Master nodes monitor the status of the cluster and command compute nodes to assign and drop segments.
+
+To create the master config file:
+
+```
+mkdir config/master
+```
+
+Under the directory we just created, create the file ```runtime.properties``` with the following contents:
+
+```
+druid.host=127.0.0.1:8082
+druid.port=8082
+druid.service=master
+
+# logging
+com.metamx.emitter.logging=true
+com.metamx.emitter.logging.level=info
+
+# zk
+druid.zk.service.host=localhost
+druid.zk.paths.base=/druid
+druid.zk.paths.discoveryPath=/druid/discoveryPath
+
+# aws (demo user)
+com.metamx.aws.accessKey=AKIAIMKECRUYKDQGR6YQ
+com.metamx.aws.secretKey=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
+
+# db
+druid.database.segmentTable=segments
+druid.database.user=druid
+druid.database.password=diurd
+druid.database.connectURI=jdbc:mysql://localhost:3306/druid
+druid.database.ruleTable=rules
+druid.database.configTable=config
+
+# master runtime configs
+druid.master.startDelay=PT60S
+```
+
+To start the master node:
+
+```bash
+java -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath lib/*:config/master com.metamx.druid.http.MasterMain
+```
+
+### Start a Compute Node ###
+
+Compute nodes are the workhorses of a cluster and are in charge of loading historical segments and making them available for queries. Our Wikipedia segment will be downloaded by a compute node.
+
+To create the compute config file:
+
+```
+mkdir config/compute
+```
+
+Under the directory we just created, create the file ```runtime.properties``` with the following contents:
+```
+druid.host=127.0.0.1:8081
+druid.port=8081
+druid.service=compute
+
+# logging
+com.metamx.emitter.logging=true
+com.metamx.emitter.logging.level=info
+
+# zk
+druid.zk.service.host=localhost
+druid.zk.paths.base=/druid
+druid.zk.paths.discoveryPath=/druid/discoveryPath
+
+# processing
+druid.processing.buffer.sizeBytes=10000000
+
+# aws (demo user)
+com.metamx.aws.accessKey=AKIAIMKECRUYKDQGR6YQ
+com.metamx.aws.secretKey=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
+
+# Path on local FS for storage of segments; dir will be created if needed
+druid.paths.indexCache=/tmp/druid/indexCache
+
+# Path on local FS for storage of segment metadata; dir will be created if needed
+druid.paths.segmentInfoCache=/tmp/druid/segmentInfoCache
+
+# server
+druid.server.maxSize=100000000
+```
+
+To start the compute node:
+
+```bash
+java -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath lib/*:config/compute com.metamx.druid.http.ComputeMain
+```
+
+### Start a Broker Node ###
+
+Broker nodes are responsible for figuring out which compute and/or realtime nodes correspond to which queries. They also merge partial results from these nodes in a scatter/gather fashion.
+
+To create the broker config file:
+
+```
+mkdir config/broker
+```
+
+Under the directory we just created, create the file ```runtime.properties``` with the following contents:
+
+```
+druid.host=127.0.0.1:8080
+druid.port=8080
+druid.service=broker
+
+# logging
+com.metamx.emitter.logging=true
+com.metamx.emitter.logging.level=info
+
+# zk
+druid.zk.service.host=localhost
+druid.zk.paths.base=/druid
+druid.zk.paths.discoveryPath=/druid/discoveryPath
+
+# thread pool size for servicing queries
+druid.client.http.connections=10
+```
+
+To start the broker node:
+
+```bash
+java -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath lib/*:config/broker com.metamx.druid.http.BrokerMain
+```
+
+## Loading the Data ##
+
+The MySQL dependency we introduced earlier on contains a 'segments' table that contains entries for segments that should be loaded into our cluster. The Druid master compares this table with segments that already exist in the cluster to determine what should be loaded and dropped. To load our wikipedia segment, we need to create an entry in our MySQL segment table.
+
+Usually, when new segments are created, these MySQL entries are created directly so you never have to do this by hand. For this tutorial, we can do this manually by going back into MySQL and issuing:
+
+```
+use druid;
+```
+
+``
+INSERT INTO segments (id, dataSource, created_date, start, end, partitioned, version, used, payload) VALUES ('wikipedia_2013-08-01T00:00:00.000Z_2013-08-02T00:00:00.000Z_2013-08-08T21:22:48.989Z', 'wikipedia', '2013-08-08T21:26:23.799Z', '2013-08-01T00:00:00.000Z', '2013-08-02T00:00:00.000Z', '0', '2013-08-08T21:22:48.989Z', '1', '{\"dataSource\":\"wikipedia\",\"interval\":\"2013-08-01T00:00:00.000Z/2013-08-02T00:00:00.000Z\",\"version\":\"2013-08-08T21:22:48.989Z\",\"loadSpec\":{\"type\":\"s3_zip\",\"bucket\":\"static.druid.io\",\"key\":\"data/segments/wikipedia/20130801T000000.000Z_20130802T000000.000Z/2013-08-08T21_22_48.989Z/0/index.zip\"},\"dimensions\":\"dma_code,continent_code,geo,area_code,robot,country_name,network,city,namespace,anonymous,unpatrolled,page,postal_code,language,newpage,user,region_lookup\",\"metrics\":\"count,delta,variation,added,deleted\",\"shardSpec\":{\"type\":\"none\"},\"binaryVersion\":9,\"size\":24664730,\"identifier\":\"wikipedia_2013-08-01T00:00:00.000Z_2013-08-02T00:00:00.000Z_2013-08-08T21:22:48.989Z\"}');
+``
+
+If you look in your master node logs, you should, after a maximum of a minute or so, see logs of the following form:
+

+Greetings! This tutorial will help clarify some core Druid concepts. We will use a realtime dataset and issue some basic Druid queries. If you are ready to explore Druid, and learn a thing or two, read on!
+
+About the data
+--------------
+
+The data source we’ll be working with is the Bit.ly USA Government website statistics stream. You can see the stream [here](http://developer.usa.gov/1usagov), and read about the stream [here](http://www.usa.gov/About/developer-resources/1usagov.shtml) . This is a feed of json data that gets updated whenever anyone clicks a bit.ly shortened USA.gov website. A typical event might look something like this:
+\`\`\`json
+{
+ [user\_agent]() “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)”,
+ [country]() “US”,
+ [known\_user]() 1,
+ [timezone]() “America/New\_York”,
+ [geo\_region]() “DC”,
+ [global\_bitly\_hash]() “17ctAFs”,
+ [encoding\_user\_bitly\_hash]() “17ctAFr”,
+ [encoding\_user\_login]() “senrubiopress”,
+ [aaccept\_language]() “en-US”,
+ [short\_url\_cname]() “1.usa.gov”,
+ [referring\_url]() “http://t.co/4Av4NUFAYq”,
+ [long\_url]() “http://www.rubio.senate.gov/public/index.cfm/fighting-for-florida?ID=c8357d12-9da8-4e9d-b00d-7168e1bf3599”,
+ [timestamp]() 1372190407,
+ [timestamp of time hash was created]() 1372190097,
+ [city]() “Washington”,
+ [latitude\_longitude]() [
+ 38.893299,
+ ~~77.014603
+ ]
+}
+\`\`\`
+The “known\_user” field is always 1 or 0. It is 1 if the user is known to the server, and 0 otherwise. We will use this field extensively in this demo.
+h2. Setting Up
+There are two ways to setup Druid: download a tarball, or ]. You only need to do one of these.
+h3. Download a Tarball
+We’ve built a tarball that contains everything you’ll need. You’ll find it [here](http://static.druid.io/artifacts/releases/druid-services-0.5.50-bin.tar.gz)
+Download this file to a directory of your choosing.
+You can extract the awesomeness within by issuing:
+\tar~~zxvf druid-services~~**~~bin.tar.gz\
+Not too lost so far right? That’s great! If you cd into the directory:
+\cd druid-services-0.5.50\
+You should see a bunch of files:
+\* run\_example\_server.sh
+\* run\_example\_client.sh
+\* LICENSE, config, examples, lib directories
+
+h2. Running Example Scripts
+Let’s start doing stuff. You can start a Druid ] node by issuing:
+\./run\_example\_server.sh\
+Select “webstream”.
+Once the node starts up you will see a bunch of logs about setting up properties and connecting to the data source. If everything was successful, you should see messages of the form shown below.
+\
+2013-07-19 21:54:05,154 INFO com.metamx.druid.realtime.RealtimeNode~~ Starting Jetty
+2013-07-19 21:54:05,154 INFO org.mortbay.log - jetty-6.1.x
+2013-07-19 21:54:05,171 INFO com.metamx.druid.realtime.plumber.RealtimePlumberSchool - Expect to run at
+2013-07-19 21:54:05,246 INFO org.mortbay.log - Started SelectChannelConnector@0.0.0.0:8083
+\
+The Druid real time-node ingests events in an in-memory buffer. Periodically, these events will be persisted to disk. If you are interested in the details of our real-time architecture and why we persist indexes to disk, I suggest you read our [White Paper](http://static.druid.io/docs/druid.pdf).
+Okay, things are about to get real. To query the real-time node you’ve spun up, you can issue:
+\./run\_example\_client.sh\
+Select “webstream” once again. This script issues ]s to the data we’ve been ingesting. The query looks like this:
+\`\`\`json
+{
+ [queryType]() “groupBy”,
+ [dataSource]() “webstream”,
+ [granularity]() “minute”,
+ [dimensions]() [
+ “timezone”
+ ],
+ [aggregations]() [
+ {
+ [type]() “count”,
+ [name]() “rows”
+ },
+ {
+ [type]() “doubleSum”,
+ [fieldName]() “known\_users”,
+ [name]() “known\_users”
+ }
+ ],
+ [filter]() {
+ [type]() “selector”,
+ [dimension]() “country”,
+ [value]() “US”
+ },
+ [intervals]() [
+ “2013-06-01T00:00/2020-01-01T00”
+ ]
+}
+\`\`\`
+This is a****groupBy**\* query, which you may be familiar with from SQL. We are grouping, or aggregating, via the **dimensions** field: . We are **filtering** via the **“country”** dimension, to only look at website hits in the US. Our **aggregations** are what we are calculating: a row count, and the sum of the number of known users in our data.
+The result looks something like this:
+\`\`\`json
+[
+ {
+ [version]() “v1”,
+ [timestamp]() “2013-07-18T19:39:00.000Z”,
+ [event]() {
+ [timezone]() “America/Chicago”,
+ [known\_users]() 10,
+ [rows]() 15
+ }
+ },
+ {
+ [version]() “v1”,
+ [timestamp]() “2013-07-18T19:39:00.000Z”,
+ [event]() {
+ [timezone]() “America/Los\_Angeles”,
+ [known\_users]() 0,
+ [rows]() 3
+ }
+ },
+…
+\`\`\`
+This groupBy query is a bit complicated and we’ll return to it later. For the time being, just make sure you are getting some blocks of data back. If you are having problems, make sure you have [curl](http://curl.haxx.se/) installed. Control+C to break out of the client script.
+h2. Querying Druid
+In your favorite editor, create the file:
+\time\_boundary\_query.body\
+Druid queries are JSON blobs which are relatively painless to create programmatically, but an absolute pain to write by hand. So anyway, we are going to create a Druid query by hand. Add the following to the file you just created:
+\
+{
+ [queryType]() “timeBoundary”,
+ [dataSource]() “webstream”
+}
+\
+The ] is one of the simplest Druid queries. To run the query, you can issue:
+\ curl~~X POST ‘http://localhost:8083/druid/v2/?pretty’ ~~H ‘content-type: application/json’~~d ```` time_boundary_query.body
+ +We get something like this JSON back: + +```json +[ + { + "timestamp": "2013-07-18T19:39:00.000Z", + "result": { + "minTime": "2013-07-18T19:39:00.000Z", + "maxTime": "2013-07-18T19:46:00.000Z" + } + } +] +``` +As you can probably tell, the result is indicating the maximum and minimum timestamps we've seen thus far (summarized to a minutely granularity). Let's explore a bit further. + +Return to your favorite editor and create the file: +
timeseries_query.body
+ +We are going to make a slightly more complicated query, the [TimeseriesQuery](TimeseriesQuery.html). Copy and paste the following into the file: +

+{
+    "queryType": "timeseries", 
+    "dataSource": "webstream", 
+    "intervals": [
+        "2010-01-01/2020-01-01"
+    ], 
+    "granularity": "all", 
+    "aggregations": [
+        {
+            "type": "count", 
+            "name": "rows"
+        }, 
+        {
+            "type": "doubleSum", 
+            "fieldName": "known_users", 
+            "name": "known_users"
+        }
+    ]
+}
+
+ +You are probably wondering, what are these [Granularities](Granularities.html) and [Aggregations](Aggregations.html) things? What the query is doing is aggregating some metrics over some span of time. +To issue the query and get some results, run the following in your command line: +
curl -X POST 'http://localhost:8083/druid/v2/?pretty' -H 'content-type: application/json'  -d  ````timeseries\_query.body
+
+
+Once again, you should get a JSON blob of text back with your results, that looks something like this: + +\`\`\`json +[ +{ + “timestamp” : “2013-07-18T19:39:00.000Z”, + “result” : { + “known\_users” : 787.0, + “rows” : 2004 + } +} +] +\`\`\` + +If you issue the query again, you should notice your results updating. + +Right now all the results you are getting back are being aggregated into a single timestamp bucket. What if we wanted to see our aggregations on a per minute basis? What field can we change in the query to accomplish this? + +If you loudly exclaimed “we can change granularity to minute”, you are absolutely correct! We can specify different granularities to bucket our results, like so: + + + { + "queryType": "timeseries", + "dataSource": "webstream", + "intervals": [ + "2010-01-01/2020-01-01" + ], + "granularity": "minute", + "aggregations": [ + { + "type": "count", + "name": "rows" + }, + { + "type": "doubleSum", + "fieldName": "known_users", + "name": "known_users" + } + ] + } + + +This gives us something like the following: + +\`\`\`json +[ + { + [timestamp]() “2013-07-18T19:39:00.000Z”, + [result]() { + [known\_users]() 33, + [rows]() 76 + } + }, + { + [timestamp]() “2013-07-18T19:40:00.000Z”, + [result]() { + [known\_users]() 105, + [rows]() 221 + } + }, + { + [timestamp]() “2013-07-18T19:41:00.000Z”, + [result]() { + [known\_users]() 53, + [rows]() 167 + } + }, +… +\`\`\` + +Solving a Problem +----------------- + +One of Druid’s main powers is to provide answers to problems, so let’s pose a problem. What if we wanted to know what the top states in the US are, ordered by the number of visits by known users over the last few minutes? To solve this problem, we have to return to the query we introduced at the very beginning of this tutorial, the [GroupByQuery](GroupByQuery.html). It would be nice if we could group by results by dimension value and somehow sort those results… and it turns out we can! + +Let’s create the file: + + group_by_query.body + and put the following in there: + 

+    {
+        "queryType": "groupBy", 
+        "dataSource": "webstream", 
+        "granularity": "all", 
+        "dimensions": [
+            "geo_region"
+        ], 
+        "orderBy": {
+            "type": "default", 
+            "columns": [
+                {
+                    "dimension": "known_users", 
+                    "direction": "DESCENDING"
+                }
+            ], 
+            "limit": 10
+        }, 
+        "aggregations": [
+            {
+                "type": "count", 
+                "name": "rows"
+            }, 
+            {
+                "type": "doubleSum", 
+                "fieldName": "known_users", 
+                "name": "known_users"
+            }
+        ], 
+        "filter": {
+            "type": "selector", 
+            "dimension": "country", 
+            "value": "US"
+        }, 
+        "intervals": [
+            "2012-10-01T00:00/2020-01-01T00"
+        ]
+    }
+    
+
+Woah! Our query just got a way more complicated. Now we have these [Filters](Filters.html) things and this [OrderBy](OrderBy.html) thing. Fear not, it turns out the new objects we’ve introduced to our query can help define the format of our results and provide an answer to our question.
+
+If you issue the query:
+
+    curl -X POST 'http://localhost:8083/druid/v2/?pretty' -H 'content-type: application/json'  -d @group_by_query.body
+
+You should see an answer to our question. For my stream, it looks like this:
+
+\`\`\`json
+[
+ {
+ [version]() “v1”,
+ [timestamp]() “2012-10-01T00:00:00.000Z”,
+ [event]() {
+ [geo\_region]() “RI”,
+ [known\_users]() 359,
+ [rows]() 143
+ }
+ },
+ {
+ [version]() “v1”,
+ [timestamp]() “2012-10-01T00:00:00.000Z”,
+ [event]() {
+ [geo\_region]() “NY”,
+ [known\_users]() 187,
+ [rows]() 322
+ }
+ },
+ {
+ [version]() “v1”,
+ [timestamp]() “2012-10-01T00:00:00.000Z”,
+ [event]() {
+ [geo\_region]() “CA”,
+ [known\_users]() 145,
+ [rows]() 466
+ }
+ },
+ {
+ [version]() “v1”,
+ [timestamp]() “2012-10-01T00:00:00.000Z”,
+ [event]() {
+ [geo\_region]() “IL”,
+ [known\_users]() 121,
+ [rows]() 185
+ }
+ },
+…
+\`\`\`
+
+Feel free to tweak other query parameters to answer other questions you may have about the data.

+What to know even more information about the Druid Cluster? Check out [Tutorial: The Druid Cluster](Tutorial:-The-Druid-Cluster.html)
+Druid is even more fun if you load your own data into it! To learn how to load your data, see [Loading Your Data](Loading-Your-Data.html).
+
+Additional Information
+----------------------
+
+This tutorial is merely showcasing a small fraction of what Druid can do. If you are interested in more information about Druid, including setting up a more sophisticated Druid cluster, please read the other links in our wiki.
+
+And thus concludes our journey! Hopefully you learned a thing or two about Druid real-time ingestion, querying Druid, and how Druid can be used to solve problems. If you have additional questions, feel free to post in our [google groups page](http://www.groups.google.com/forum/#!forum/druid-development).

+Greetings! We see you’ve taken an interest in Druid. That’s awesome! Hopefully this tutorial will help clarify some core Druid concepts. We will go through one of the Real-time [Examples](Examples.html), and issue some basic Druid queries. The data source we’ll be working with is the [Twitter spritzer stream](https://dev.twitter.com/docs/streaming-apis/streams/public). If you are ready to explore Druid, brave its challenges, and maybe learn a thing or two, read on!
+
+Setting Up
+----------
+
+There are two ways to setup Druid: download a tarball, or build it from source.
+
+### Download a Tarball
+
+We’ve built a tarball that contains everything you’ll need. You’ll find it [here](http://static.druid.io/data/examples/druid-services-0.4.6.tar.gz).
+Download this bad boy to a directory of your choosing.
+
+You can extract the awesomeness within by issuing:
+
+    tar -zxvf druid-services-0.4.6.tar.gz
+
+Not too lost so far right? That’s great! If you cd into the directory:
+
+    cd druid-services-0.4.6-SNAPSHOT
+
+You should see a bunch of files:
+\* run\_example\_server.sh
+\* run\_example\_client.sh
+\* LICENSE, config, examples, lib directories
+
+### Clone and Build from Source
+
+The other way to setup Druid is from source via git. To do so, run these commands:
+
+\`\`\`
+git clone git@github.com:metamx/druid.git
+cd druid
+git checkout druid-0.4.32-branch
+./build.sh
+\`\`\`
+
+You should see a bunch of files:
+
+\`\`\`
+DruidCorporateCLA.pdf README common examples indexer pom.xml server
+DruidIndividualCLA.pdf build.sh doc group\_by.body install publications services
+LICENSE client eclipse\_formatting.xml index-common merger realtime
+\`\`\`
+
+You can find the example executables in the examples/bin directory:
+\* run\_example\_server.sh
+\* run\_example\_client.sh
+
+Running Example Scripts
+-----------------------
+
+Let’s start doing stuff. You can start a Druid [Realtime](Realtime.html) node by issuing:
+
+    ./run_example_server.sh
+
+Select “twitter”.
+
+You’ll need to register a new application with the twitter API, which only takes a minute. Go to [https://twitter.com/oauth\_clients/new](https://twitter.com/oauth_clients/new) and fill out the form and submit. Don’t worry, the home page and callback url can be anything. This will generate keys for the Twitter example application. Take note of the values for consumer key/secret and access token/secret.
+
+Enter your credentials when prompted.
+
+Once the node starts up you will see a bunch of logs about setting up properties and connecting to the data source. If everything was successful, you should see messages of the form shown below. If you see crazy exceptions, you probably typed in your login information incorrectly.
+
+

+The logs are about building different columns, probably not the most exciting stuff (they might as well be in Vulcan) if are you learning about Druid for the first time. Nevertheless, if you are interested in the details of our real-time architecture and why we persist indexes to disk, I suggest you read our [White Paper](http://static.druid.io/docs/druid.pdf).
+
+Okay, things are about to get real (~~time). To query the real-time node you’ve spun up, you can issue:
+\./run\_example\_client.sh\
+Select “twitter” once again. This script issues ]s to the twitter data we’ve been ingesting. The query looks like this:
+\`\`\`json
+{
+ [queryType]() “groupBy”,
+ [dataSource]() “twitterstream”,
+ [granularity]() “all”,
+ [dimensions]() ,
+ [aggregations]([)
+ { [type]() “count”, [name]() “rows”},
+ { [type]() “doubleSum”, [fieldName]() “tweets”, [name]() “tweets”}
+ ],
+ [filter]() { [type]() “selector”, [dimension]() “lang”, [value]() “en” },
+ [intervals](["2012-10-01T00:00/2020-01-01T00"])
+}
+\`\`\`
+This is a **groupBy** query, which you may be familiar with from SQL. We are grouping, or aggregating, via the **dimensions** field: . We are **filtering** via the **“lang”** dimension, to only look at english tweets. Our **aggregations** are what we are calculating: a row count, and the sum of the tweets in our data.
+The result looks something like this:
+\`\`\`json
+[
+ {
+ [version]() “v1”,
+ [timestamp]() “2012-10-01T00:00:00.000Z”,
+ [event]() {
+ [utc\_offset]() “~~10800",
+ [tweets]() 90,
+ [lang]() "en",
+ [rows]() 81
+ }
+ },
+ {
+ [version]() "v1",
+ [timestamp]() "2012-10-01T00:00:00.000Z",
+ [event]() {
+ [utc\_offset]() "~~14400”,
+ [tweets]() 177,
+ [lang]() “en”,
+ [rows]() 154
+ }
+ },
+…
+\`\`\`
+This data, plotted in a time series/distribution, looks something like this:
+![Timezone / Tweets Scatter Plot](http://metamarkets.com/wp-content/uploads/2013/06/tweets_timezone_offset.png "Timezone / Tweets Scatter Plot")
+This groupBy query is a bit complicated and we’ll return to it later. For the time being, just make sure you are getting some blocks of data back. If you are having problems, make sure you have [curl](http://curl.haxx.se/) installed. Control+C to break out of the client script.
+h2. Querying Druid
+In your favorite editor, create the file:
+\time\_boundary\_query.body\
+Druid queries are JSON blobs which are relatively painless to create programmatically, but an absolute pain to write by hand. So anyway, we are going to create a Druid query by hand. Add the following to the file you just created:
+\
+\
+The ] is one of the simplest Druid queries. To run the query, you can issue:
+\ curl~~X POST ‘http://localhost:8080/druid/v2/?pretty’ ~~H ‘content-type: application/json’~~d ```` time_boundary_query.body
+ +We get something like this JSON back: + +```json +[ { + "timestamp" : "2013-06-10T19:09:00.000Z", + "result" : { + "minTime" : "2013-06-10T19:09:00.000Z", + "maxTime" : "2013-06-10T20:50:00.000Z" + } +} ] +``` +That's the result. What information do you think the result is conveying? +... +If you said the result is indicating the maximum and minimum timestamps we've seen thus far (summarized to a minutely granularity), you are absolutely correct. I can see you are a person legitimately interested in learning about Druid. Let's explore a bit further. + +Return to your favorite editor and create the file: +
timeseries_query.body
+ +We are going to make a slightly more complicated query, the [TimeseriesQuery](TimeseriesQuery.html). Copy and paste the following into the file: +
{
+  "queryType":"timeseries",
+  "dataSource":"twitterstream",
+  "intervals":["2010-01-01/2020-01-01"],
+  "granularity":"all",
+  "aggregations":[
+      { "type": "count", "name": "rows"},
+      { "type": "doubleSum", "fieldName": "tweets", "name": "tweets"}
+  ]
+}
+
+ +You are probably wondering, what are these [Granularities](Granularities.html) and [Aggregations](Aggregations.html) things? What the query is doing is aggregating some metrics over some span of time. +To issue the query and get some results, run the following in your command line: +
curl -X POST 'http://localhost:8080/druid/v2/?pretty' -H 'content-type: application/json'  -d  ````timeseries\_query.body
+
+
+Once again, you should get a JSON blob of text back with your results, that looks something like this: + +\`\`\`json +[ { + “timestamp” : “2013-06-10T19:09:00.000Z”, + “result” : { + “tweets” : 358562.0, + “rows” : 272271 + } +} ] +\`\`\` + +If you issue the query again, you should notice your results updating. + +Right now all the results you are getting back are being aggregated into a single timestamp bucket. What if we wanted to see our aggregations on a per minute basis? What field can we change in the query to accomplish this? + +If you loudly exclaimed “we can change granularity to minute”, you are absolutely correct again! We can specify different granularities to bucket our results, like so: + +\`\`\`json +{ + [queryType]("timeseries"), + [dataSource]("twitterstream"), + [intervals](["2010-01-01/2020-01-01"]), + [granularity]("minute"), + [aggregations]([) + { [type]() “count”, [name]() “rows”}, + { [type]() “doubleSum”, [fieldName]() “tweets”, [name]() “tweets”} + ] +} +\`\`\` + +This gives us something like the following: + +\`\`\`json +[ { + “timestamp” : “2013-06-10T19:09:00.000Z”, + “result” : { + “tweets” : 2650.0, + “rows” : 2120 + } +}, { + “timestamp” : “2013-06-10T19:10:00.000Z”, + “result” : { + “tweets” : 3401.0, + “rows” : 2609 + } +}, { + “timestamp” : “2013-06-10T19:11:00.000Z”, + “result” : { + “tweets” : 3472.0, + “rows” : 2610 + } +}, +… +\`\`\` + +Solving a Problem +----------------- + +One of Druid’s main powers (see what we did there?) is to provide answers to problems, so let’s pose a problem. What if we wanted to know what the top hash tags are, ordered by the number tweets, where the language is english, over the last few minutes you’ve been reading this tutorial? To solve this problem, we have to return to the query we introduced at the very beginning of this tutorial, the [GroupByQuery](GroupByQuery.html). It would be nice if we could group by results by dimension value and somehow sort those results… and it turns out we can! + +Let’s create the file: + + group_by_query.body + and put the following in there: + 
{
+        "queryType": "groupBy",
+        "dataSource": "twitterstream",
+        "granularity": "all",
+        "dimensions": ["htags"],
+        "orderBy": {"type":"default", "columns":[{"dimension": "tweets", "direction":"DESCENDING"}], "limit":5},
+        "aggregations":[
+          { "type": "longSum", "fieldName": "tweets", "name": "tweets"}
+        ],
+        "filter": {"type": "selector", "dimension": "lang", "value": "en" },
+        "intervals":["2012-10-01T00:00/2020-01-01T00"]
+    }
+    
+
+Woah! Our query just got a way more complicated. Now we have these [Filters](Filters.html) things and this [OrderBy](OrderBy.html) thing. Fear not, it turns out the new objects we’ve introduced to our query can help define the format of our results and provide an answer to our question.
+
+If you issue the query:
+
+    curl -X POST 'http://localhost:8080/druid/v2/?pretty' -H 'content-type: application/json'  -d @group_by_query.body
+
+You should hopefully see an answer to our question. For my twitter stream, it looks like this:
+
+\`\`\`json
+[ {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “tweets” : 2660,
+ “htags” : “android”
+ }
+}, {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “tweets” : 1944,
+ “htags” : “E3”
+ }
+}, {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “tweets” : 1927,
+ “htags” : “15SueñosPendientes”
+ }
+}, {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “tweets” : 1717,
+ “htags” : “ipad”
+ }
+}, {
+ “version” : “v1”,
+ “timestamp” : “2012-10-01T00:00:00.000Z”,
+ “event” : {
+ “tweets” : 1515,
+ “htags” : “IDidntTextYouBackBecause”
+ }
+} ]
+\`\`\`
+
+Feel free to tweak other query parameters to answer other questions you may have about the data.

+Additional Information
+----------------------
+
+This tutorial is merely showcasing a small fraction of what Druid can do. Next, continue on to [Loading Your Data](Loading Your Data.html).
+
+And thus concludes our journey! Hopefully you learned a thing or two about Druid real-time ingestion, querying Druid, and how Druid can be used to solve problems.

+This page discusses how we do versioning and provides information on our stable releases.
+
+Versioning Strategy
+-------------------
+
+We generally follow [semantic versioning](http://semver.org/). The general idea is
+
+-   “Major” version (leftmost): backwards incompatible, no guarantees exist about APIs between the versions
+-   “Minor” version (middle number): you can move forward from a smaller number to a larger number, but moving backwards *might* be incompatible.
+-   “bug-fix” version (“patch” or the rightmost): Interchangeable. The higher the number, the more things are fixed (hopefully), but the programming interfaces are completely compatible and you should be able to just drop in a new jar and have it work.
+
+Note that this is defined in terms of programming API, **not** in terms of functionality. It is possible that a brand new awesome way of doing something is introduced in a “bug-fix” release version if it doesn’t add to the public API or change it.
+
+One exception for right now, while we are still in major version 0, we are considering the APIs to be in beta and are conflating “major” and “minor” so a minor version increase could be backwards incompatible for as long as we are at major version 0. These will be communicated via email on the group.
+
+For external deployments, we recommend running the stable release tag. Releases are considered stable after we have deployed them into our production environment and they have operated bug-free for some time.
+
+Tagging strategy
+----------------
+
+Tags of the codebase are equivalent to release candidates. We tag the code every time we want to take it through our release process, which includes some QA cycles and deployments. So, it is not safe to assume that a tag is a stable release, it is a solidification of the code as it goes through our production QA cycle and deployment. Tags will never change, but we often go through a number of iterations of tags before actually getting a stable release onto production. So, it is recommended that if you are not aware of what is on a tag, to stick to the stable releases listed on the [Download](Download.html) page.

+Druid uses ZooKeeper (ZK) for management of current cluster state. The operations that happen over ZK are
+
+1.  [Master](Master.html) leader election
+2.  Segment “publishing” protocol from [Compute](Compute.html) and [Realtime](Realtime.html)
+3.  Segment load/drop protocol between [Master](Master.html) and [Compute](Compute.html)
+
+### Property Configuration
+
+ZooKeeper paths are set via the `runtime.properties` configuration file. Druid will automatically create paths that do not exist, so typos in config files is a very easy way to become split-brained.
+
+There is a prefix path that is required and can be used as the only (well, kinda, see the note below) path-related zookeeper configuration parameter (everything else will be a default based on the prefix):
+
+    druid.zk.paths.base
+
+You can also override each individual path (defaults are shown below):
+
+    druid.zk.paths.propertiesPath=${druid.zk.paths.base}/properties
+    druid.zk.paths.announcementsPath=${druid.zk.paths.base}/announcements
+    druid.zk.paths.servedSegmentsPath=${druid.zk.paths.base}/servedSegments
+    druid.zk.paths.loadQueuePath=${druid.zk.paths.base}/loadQueue
+    druid.zk.paths.masterPath=${druid.zk.paths.base}/master
+    druid.zk.paths.indexer.announcementsPath=${druid.zk.paths.base}/indexer/announcements
+    druid.zk.paths.indexer.tasksPath=${druid.zk.paths.base}/indexer/tasks
+    druid.zk.paths.indexer.statusPath=${druid.zk.paths.base}/indexer/status
+    druid.zk.paths.indexer.leaderLatchPath=${druid.zk.paths.base}/indexer/leaderLatchPath
+
+NOTE: We also use Curator’s service discovery module to expose some services via zookeeper. This also uses a zookeeper path, but this path is **not** affected by `druid.zk.paths.base` and **must** be specified separately. This property is
+
+    druid.zk.paths.discoveryPath
+
+### Master Leader Election
+
+We use the Curator LeadershipLatch recipe to do leader election at path
+
+    ${druid.zk.paths.masterPath}/_MASTER
+
+### Segment “publishing” protocol from Compute and Realtime
+
+The `announcementsPath` and `servedSegmentsPath` are used for this.
+
+All [Compute](Compute.html) and [Realtime](Realtime.html) nodes publish themselves on the `announcementsPath`, specifically, they will create an ephemeral znode at
+
+    ${druid.zk.paths.announcementsPath}/${druid.host}
+
+Which signifies that they exist. They will also subsequently create a permanent znode at
+
+    ${druid.zk.paths.servedSegmentsPath}/${druid.host}
+
+And as they load up segments, they will attach ephemeral znodes that look like
+
+    ${druid.zk.paths.servedSegmentsPath}/${druid.host}/_segment_identifier_
+
+Nodes like the [Master](Master.html) and [Broker](Broker.html) can then watch these paths to see which nodes are currently serving which segments.
+
+### Segment load/drop protocol between Master and Compute
+
+The `loadQueuePath` is used for this.
+
+When the [Master](Master.html) decides that a [Compute](Compute.html) node should load or drop a segment, it writes an ephemeral znode to
+
+    ${druid.zk.paths.loadQueuePath}/_host_of_compute_node/_segment_identifier
+
+This node will contain a payload that indicates to the Compute node what it should do with the given segment. When the Compute node is done with the work, it will delete the znode in order to signify to the Master that it is complete.

- * located in the classpath.
- * 

- * The design rules are noted here with rationale
- * 

- * 

- * 
- * Design Rule Notes:
- * (a) Properties set on the commandline of services take precedence over  runtime.properties which
- *       takes precedence over properties stored in zookeeper.
- *
- *       Rationale:  organizing principle.
- *
- * (a) Services load properties on startup only.
- *
- *       Rationale: stepwise changes are safer and easier to manage.
- *
- * (b) Only DruidSetup creates properties and znode paths (zpaths) on zookeeper and no other tool or service
- *       will make ensemble-wide settings automatically.
- *
- *       Rationale: one place for this logic, under manual control, and avoid accidental
- *       namespace/partition creation.
- *
- * (c) DruidSetup creates reasonable zpaths but supports overrides to enable tactical
- *   version transitions (just in case).  If zpaths are overridden, then they must all be
- *   overridden together since they are not independent.
- *
- *       Rationale:  convention beats configuration most of the time; sometimes configuration is needed
- *       negotiate unusual cases.
- *
- * (d) Properties settings stored on zookeeper are not cumulative; previous properties are removed before
- *   new ones are stored.
- *       Rationale:  Keep the operations at the granularity of a file of properties, avoid
- *       dependence on order of setup operations, enable dumping of current settings.
