ElasticSearch Component
Available as of Camel 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>

Message Operations
The following ElasticSearch operations are currently supported. Simply set an endpoint URI option or an exchange header with name 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. From 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 (Map, String, byte[] or XContentBuilder). | From Camel 2.14: Adds content to an index and return a List of the id's of the successfully indexed documents in the body. |
BULK
| A List or Collection of any type that is already accepted (Map, String, byte[] or XContentBuilder). | From Camel 2.15: Adds content to an index and returns the BulkResponse object in the body. |
SEARCH
| Map or SearchRequest object.
| From Camel 2.15: Search the content with the Map or query string. |
MULTIGET
| List of MultigetRequest.Item object.
| From Camel 2.17: Retrieves the specified indexes type's specified in MultigetRequest and returns a MultigetResponse object in the body. |
MULTISEARCH
| List of SearchRequest object.
| From Camel 2.17: Search for parameters specified in MultiSearchRequest and returns a MultiSearchResponse object in the body. |
EXISTS
| Index name as a header. | From Camel 2.17: Returns a Boolean object in the body. |
UPDATE
| Map, String, byte[] or XContentBuilder content to update.
| From Camel 2.17: Updates content to an index and returns the content's indexId in the body. |
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);
