elasticsearch-types

Elasticsearch-types provides a simple way of generating valid Elasticsearch Mapping of your POJOs as Elasticsearch Types, allowing for you to have your configuration of your types where your code resides.

Code Example

package my.cool.elasticsearch.project

@ESType(name = "MyESType")
public class MyPojo{
  
  @StringType(analyzer = "standard_en", store = true)
  private String myToken = "My Pojo Rocks"
  
  @NumericType(type = long)
  private long mySerialNumer = 1337L;
  //... and so forth 
}

package my.uber.elasticsearch.project

public class ElasticSearchIndexer {

  //Returns a valid JSON-string 
 
  Map<String, String> mapping = MappingProducer.getMapping("my.cool.elasticsearch");
  mapping.keySet().stream()
        .map(
          (type) ->esClient
                  .admin()
                  .indices()
                  .preparePutMapping(index)
                  .setType(type)
                  .setSource(mapping.get(type))
                  .execute()
                  .actionGet()
          )
        .forEach((mappingResponse) -> {
              boolean acknowledged = mappingResponse.isAcknowledged();
  });
      
  
}

Motivation

Elasticsearch is quite a powerful and API-rich search and analytics engine. Elasticsearch does not provide a lightweight Java-client (that doesnt ship the entire search engine as a JAR). Thirdparty clients such as JEST are addressing this issue, but still requires you to generate quite a bit of JSON-strings interact with your ES instance. JSON-strings in Java aren't a match made in heaven for code readability and testing. Elasticsearch-types aim to fill address this issue somewhat by addressing the Mapping issues, that quickly can get out of hand if a client has to deal with many different dataobjects.

Installation

Requirements

• Maven
• Git
• minimum Java 8

For now, clone this repository, run

git clone git@github.com:ebbesson/elasticsearch-types.git
cd elastic-types
mvn install;

API Reference

Annotation types are mapped towards Elasticsearch Field types

Currently Elastic Types (0.1.0) only supports

• String
• Numeric
• Date

but more types will be added
