Elasticsearch Extension

The goal of an extension goes beyond the Artemis API-core, and with Elasticsearch Extensions it does not look different. Elasticsearch Extension has classes such as ElasticsearchDocumentRepository and ElasticsearchDocumentRepositoryAsync whose have support to Elasticsearch particular behavior as query builder.

Maven Dependency

To use the Elasticsearch extension to Artemis:

 
  <dependency>
    <groupId>org.jnosql.artemis</groupId>
    <artifactId>elasticsearch-extension</artifactId>
    <version>version</version>
  </dependency>

E.g:

 
  <dependency>
    <groupId>org.jnosql.artemis</groupId>
    <artifactId>elasticsearch-extension</artifactId>
    <version>0.0.1</version>
  </dependency>

Elastisearch Document Repository

ElasticsearchDocumentRepositoryAsync and ElasticsearchDocumentRepository are specialized classes from DocumentRepository and DocumentRepositoryAsync respectively, so they have all methods plus the Elasticsearch methods whose has in Elasticsearch driver such as ES query builder. To active, this resource just needs to produce an ElasticsearchDocumentCollectionManager in a CDI context.

  @Produces
    public ElasticsearchDocumentCollectionManager getManager() {
	//code
        return managerFactory.get(KEY_SPACE);
    }

Done, the Artemis will take and manage the bean to you.

@Inject
private ElasticsearchDocumentRepository columnRepository;

public void sample() {
        QueryBuilder queryBuilder = boolQuery().filter(termQuery("name", "Ada"));
        List<Person> people = repository.find(queryBuilder, "Person");
}

The similar thing happens with the CassandraColumnRepositoryAsync just produces the CassandraColumnFamilyManagerAsync.

  @Produces
    public ElasticsearchDocumentCollectionManagerAsync getManagerAsync() {
	//code
        return managerFactory.get(KEY_SPACE);
    }
