Chapter 93. Elasticsearch Component (deprecated) Available as of Camel version 2.11 The ElasticSearch component allows you to interface with an ElasticSearch server. Maven users will need to add the following dependency to their pom.xml for this component: <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-elasticsearch</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> 93.1. URI format elasticsearch://clusterName[?options] 93.2. Endpoint Options The Elasticsearch component supports 2 options, which are listed below. Name Description Default Type client (advanced) To use an existing configured Elasticsearch client, instead of creating a client per endpoint. Client resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean The Elasticsearch endpoint is configured using URI syntax: with the following path and query parameters: 93.2.1. Path Parameters (1 parameters): Name Description Default Type clusterName Required Name of cluster or use local for local mode String 93.2.2. Query Parameters (11 parameters): Name Description Default Type clientTransportSniff (producer) Is the client allowed to sniff the rest of the cluster or not (default true). This setting map to the client.transport.sniff setting. true Boolean consistencyLevel (producer) The write consistency level to use with INDEX and BULK operations (can be any of ONE, QUORUM, ALL or DEFAULT) DEFAULT WriteConsistencyLevel data (producer) Is the node going to be allowed to allocate data (shards) to it or not. This setting map to the node.data setting. Boolean indexName (producer) The name of the index to act against String indexType (producer) The type of the index to act against String ip (producer) The TransportClient remote host ip to use String operation (producer) What operation to perform String pathHome (producer) The path.home property of ElasticSearch configuration. You need to provide a valid path, otherwise the default, USDuser.home/.elasticsearch, will be used. USD{user.home}/.elasticsearch String port (producer) The TransportClient remote port to use (defaults to 9300) 9300 int transportAddresses (producer) Comma separated list with ip:port formatted remote transport addresses to use. The ip and port options must be left blank for transportAddresses to be considered instead. String synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean 93.3. Spring Boot Auto-Configuration The component supports 3 options, which are listed below. Name Description Default Type camel.component.elasticsearch.client To use an existing configured Elasticsearch client, instead of creating a client per endpoint. The option is a org.elasticsearch.client.Client type. String camel.component.elasticsearch.enabled Enable elasticsearch component true Boolean camel.component.elasticsearch.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean 93.4. Local testing If you want to run against a local (in JVM/classloader) ElasticSearch server, just set the clusterName value in the URI to "local". See the client guide for more details. 93.5. Message Operations The following ElasticSearch operations are currently supported. Simply set an endpoint URI option or exchange header with a key of "operation" and a value set to one of the following. Some operations also require other parameters or the message body to be set. operation message body description INDEX Map, String, byte[] or XContentBuilder content to index adds content to an index and returns the content's indexId in the body. Camel 2.15, you can set the indexId by setting the message header with the key "indexId". GET_BY_ID index id of content to retrieve retrieves the specified index and returns a GetResult object in the body DELETE index id of content to delete deletes the specified indexId and returns a DeleteResult object in the body BULK_INDEX a List or Collection of any type that is already accepted (XContentBuilder, Map, byte[], String) *Camel 2.14,*adds content to an index and return a List of the id of the successfully indexed documents in the body BULK a List or Collection of any type that is already accepted (XContentBuilder, Map, byte[], String) Camel 2.15: Adds content to an index and returns the BulkResponse object in the body SEARCH Map or SearchRequest Object Camel 2.15: search the content with the map of query string MULTIGET List of MultigetRequest.Item object Camel 2.17: retrieves the specified indexes, types etc. in MultigetRequest and returns a MultigetResponse object in the body MULTISEARCH List of SearchRequest object Camel 2.17: search for parameters specified in MultiSearchRequest and returns a MultiSearchResponse object in the body EXISTS Index name as header Camel 2.17: Returns a Boolean object in the body UPDATE Map, String, byte[] or XContentBuilder content to update Camel 2.17: Updates content to an index and returns the content's indexId in the body. 93.6. Index Example Below is a simple INDEX example from("direct:index") .to("elasticsearch://local?operation=INDEX&indexName=twitter&indexType=tweet"); <route> <from uri="direct:index" /> <to uri="elasticsearch://local?operation=INDEX&indexName=twitter&indexType=tweet"/> </route> A client would simply need to pass a body message containing a Map to the route. The result body contains the indexId created. Map<String, String> map = new HashMap<String, String>(); map.put("content", "test"); String indexId = template.requestBody("direct:index", map, String.class); 93.7.
