This should list the values exactly as you feed them into the API like "native" or "msq". Does this property only apply if useSupervisors: true? if so it should be noted.

Yes, should have kept this PR in draft. Still working on the docs.
But yes, the result of the GET is the correct format.

maybe should this clarify that this is the default if not specified in the datasource specific config?

Yes, fair point. Let me update that.

i think maybe this should be split out and documented as a CompactionPolicy since it is specific to newestSegmentFirst in case we ever add other policies (or make this one more flexible or whatever)

Yeah, that makes sense.

@vogievetsky , had you updated the config in a prior API call to use The update API I would personally prefer if both of these APIs (or atleast the new one) just updated the whole object Please let me know what you think. I will make the necessary changes. |

Yes, I have previously set engine to msq. I guess I always imagined all these APIs to take a entire object, validate it, and then set it. That was my mental model for the |

Sounds good. Thanks for the clarification, @vogievetsky . |
|
@vogievetsky , I am merging this PR for now. |

Thank you for addressing my feedback. I think a separate API to fetch just the cluster config would be really great. The current API is very messy. |

Changes Add retries to TransactionalSegmentPublisher Add field retryable to SegmentPublishResult Remove class DataStoreMetadataUpdateResult and use SegmentPublishResult instead * Add the capability to turboload segments onto historicals (#17775) Add the capability to set Historicals into a turbo loading mode, to focus on loading segments at the cost of query performance. Context -------- Currently, when a new Historical is started, it initially starts out using a bootstrap thread pool. It uses this thread pool to load any existing cached segments and broadcast segments. Once it loads any segments from both these sources, the historical switches to a smaller thread-pool and begins to serve queries. In certain cases, it would be useful to have the historical switch back to this mode, and focus on loading segments, either to continue loading the initial non-bootstrap segments, or to catch up with assigned segments. This PR adds a coordinator dynamic config that allows servers to be configured to use the larger bootstrap threadpool to load segments faster. Changes --------- - Added a new dynamic coordinator configuration, `turboLoadingNodes`. - Ignore `druid.coordinator.loadqueuepeon.http.batchSize` for servers in `turboLoadingNodes` - Add API on historical to return loading capabilities i.e. num loading threads in normal and turbo mode * Fix resource leak for GroupBy query merge buffer when query matched result cache (#17823) * Fix resource leak for GroupBy query merge buffer when match result cache * Fix resource leak for GroupBy query merge buffer when match result cache * Add test * Add test * Add comment * Add test * Add metric and simulation test for turbo loading mode (#17830) Changes --------- - Add field `loadingMode` to `SegmentChangeStatus` - Including loading mode in `DataSegmentChangeResponse` - Include loading mode in the `description` of metrics emitted from `HttpLoadQueuePeon` - Add simulation test to verify loading mode metrics * Update query example (#17811) * String util upgrade for jdk9+ (#17795) * Update StringUtils.replace() after fix in JDK9 * Upgrade optimized string replace algorithm * Update methods by re-using declared StringUtils#replace method * Replace hard-coded UTF-8 encodings with StandardCharsets * Documentation Fix (#17826) * Enable to run quidem tests against multiple configurations; add conditionals; cleanup framework init (#17829) * cleans up `SqlTestFramework` initialization to leave the `OverrideModule` empty - so that tests could more easily take over parts * remove the `QueryComponentSupplier#createEngine` factory method - instead uses a `Class<SqlEngine>` and use the `injector` to initialize it * enables the usage of `!disabled <supplier> <message>` - to mark cases which are not yet supported with a specific configuration for some reason * fixes that `datasets` was not respecting the `rollup` specification of the ingest * enables to use `MultiComponentSupplier` backed tests - these will turn into matrix tests over multiple componentsuppliers - enabling running the same testcase in different scenarios * Fix failing test in DimensionSchemaUtilsTest (#17832) * Improve performance of segment metadata cache on Overlord (#17785) Description ----------- #17653 introduces a cache for segment metadata on the Overlord. This patch is a follow up to that to make the cache more robust, performant and debug-friendly. Changes --------- - Do not cache unused segments This significantly reduces sync time in cases where the cluster has a lot of unused segments. Unused segments are needed only during segment allocation to ensure that a duplicate ID is not allocated. This is a rare DB query which is supported by sufficient indexes and thus need not be cached at the moment. - Update cache directly when segments are marked as unused to avoid race conditions with DB sync. - Fix NPE when using segment metadata cache with concurrent locks. - Atomically update segment IDs and pending segments in a `HeapMemoryDatasourceSegmentCache` using methods `syncSegmentIds()` and `syncPendingSegments()` rather than updating one by one. This ensures that the locks are held for a shorter period and the update made to the cache is atomic. Main updated classes ---------------------- - `IndexerMetadataStorageCoordinator` - `OverlordDataSourcesResource` - `HeapMemorySegmentMetadataCache` - `HeapMemoryDatasourceSegmentCache` Cleaner cache sync -------------------- In every sync, the following steps are performed for each datasource: - Retrieve ALL used segment IDs from metadata store - Atomically update segment IDs in cache and determine list of segment IDs which need to be refreshed. - Fetch payloads of segments that need to be refreshed - Atomically update fetched payloads into the cache - Fetch ALL pending segments - Atomically update pending segments into the cache - Clean up empty intervals from datasource caches * GroupBy: Fix offsets on outer queries. (#17837) Prior to this patch, an offset specified on a groupBy that itself has an inner groupBy would lead to an error like "Cannot push down offsets". This happened because of a violated assumption: the processing logic assumes that offsets have been pushed into limits (so limit pushdown optimizations can safely be used). This patch adjusts processing to incorporate offsets into limits during processing of subqueries. Later on, in post-processing, offsets are applied as written. * Enable build cache for web-console (#17831) * run audit fix (#17836) * Do not block task actions on Overlord if segment metadata cache is syncing (#17824) * Do not use segment metadata cache until leader has synced * Read from cache only when synced, but write even if sync is pending * Fix compilation * Fix checkstyle, test * Revert some extra changes * Add 3 modes of cache usage * Move enum to SegmentMetadataCache * Run tests in all 3 cache modes * Fix docs and IT configs * Fix config binding * Remove forbidden api * Fix typos, docs and enum casing * Fix doc * Add json, array, aggregation function tests to quidem (#17842) This PR adds the sql-native portion of the json, array, and aggregation function tests to quidem. It adds a total of 9965 queries, with 6752 positive tests and 3213 negative tests. * Optionally include Content-Disposition header in statement results API response (#17840) Adds support for an optional filename query parameter to the /druid/v2/sql/statements/{queryId}/results API. When provided, the response will include a header Content-Disposition: attachment; filename="{filename}", which will instruct a web browser to save the response as a file rather than displaying it inline. This save-as-attachment behavior could be achieved by adding a "download" attribute to the results link, but this only works for same-origin URLs (as in the Web Console). If the UI origin is different from the Druid API origin, browsers will ignore the attribute and serve the results inline, which is poor UX for files that are potentially very large. For the sake of consistency, all successful responses in SqlStatementResource.doGetResults may include this header, even if there are no results. Release note Improved: The "Get query results" statements API supports an optional filename query parameter. When provided, the response will instruct web browsers to save the results as a file instead of showing them inline (via the Content-Disposition header). * Web console: download follow up (#17845) * set filename * update download button * added markdown support * add test * better download * fix TSV * better download behaviour and tests * always show download all button * Fix flaky unit tests in SegmentBootstrapperTest and KinesisIndexTaskTest (#17841) Changes: - Fix flakiness in SegmentBootstrapperTest - Make TestSegmentCacheManager thread safe by moving from ArrayList to CopyOnWriteArrayList - Modify assertions to disregard list ordering since order of list modifications is not always deterministic - Fix flaky KinesisIndexTask tests. * Web console: responding to user feedback about the explore view and fixing bugs (#17844) * better debounce * better cumpose filter * hook up preview filters * better stack handling * fix some props * refactor stack to facet * fix hover part 1 * line hover part 2 * start adding moduleWhere * info popover * add filter icon * toggle button * module filter bar * update TestSegmentCacheManager * revert some style changes * validate datasource in CachingClusteredClient as well * fix build failure and update style * changes * add inlineds test * add sanity check on segment * inject policy enforcer * add PolicyEnforcer binding in MSQTestBase * add check in SinkQuerySegmentWalker * more tests in realtime server * revert config change in examples * revert config change in integration test config * more tests in msq * another test for unnest in msq * add support for policy from extension * more test * refactor MSQTaskQueryMakerTest to use an instance of MSQTaskQueryMaker * Add test for JoinDataSource * add policyEnforcer to withPolicies, and validate segment after segment mapping * fix binding and test * add policy module * mock planner toolbox * revert some injection * add test for stream appenderator * update PolicyEnforcer to take ReferenceCountingSegment as param * update to QueryLifecycleTest * update to SqlTestFramework * pass enforcer to BroadcastJoinSegmentMapFnProcessor and add test.

Description
#16768 introduces the option to run compaction as a supervisor on Overlord instead of via coordinator duties.
It also packages several improvements over the traditional compaction duty, such as support for using
the MSQ engine to launch compaction tasks.
However, that patch relies on an Overlord runtime property to enable/disable this feature, which can be
cumbersome and error prone, given that both Coordinator and Overlord need to be aware of it.
It also leads to a poorer design since half of compaction-related features are controlled by the compaction
dynamic config whereas the other half is controlled by the runtime properties.
This patch reconciles the two by simply using compaction dynamic config for all purposes.
It has the added benefit of allowing a quick switch between Overlord supervisor and Coordinator duty,
for ease of testing and in case of unexpected behaviour in production.
