# Elasticsearch Consumer A consumer that allows you to index document records into Elasticsearch. ## Beans for injection You can import `ElasticsearchConsumerConfiguration` in the application and then inject the following bean. `Consumer<Message<?>> elasticsearchConsumer` After injecting this `Consumer` bean in the application, it's `accept` method can be called programmatically to index Elasticsearch documents. This consumer only supports indexing documents with JSON formats. The JSON document can be provided using one of the following methods. * JSON string * `java.util.Map` * `XContentBuilder` provided by Elasticsearch ## Configuration Options All configuration properties are prefixed with `elasticsearch.consumer`. For more information on the various options available, please see link:src/main/java/org/springframework/cloud/fn/consumer/elasticsearch/ElasticsearchConsumerConfiguration.java[ElasticsearchConsumerProperties]. In addition to these options, the consumer makes use of Spring Boot autoconfiguration for Elasticsearch. Therefore you need to use https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/elasticsearch/ElasticsearchRestClientProperties.java[these properties] for configuration Elasticsearch. See this https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-elasticsearch[section] from Spring Boot docs. ## Examples See this link:src/test/java/org/springframework/cloud/fn/consumer/elasticsearch/ElasticsearchConsumerApplicationTests.java[test suite] for seeing the Elasticsearch consumer in action. ## Other usage See this https://github.com/spring-cloud/stream-applications/blob/master/applications/sink/elasticsearch-sink/README.adoc[README] where this consumer is used for creating an Elasticsearch sink.
