CouchDB

Camel CouchDB component

Available as of Camel 2.11

The couchdb: component allows you to treat CouchDB instances as a producer or consumer of messages. Using the lightweight LightCouch API, this camel component has the following features:

As a consumer, monitors couch changesets for inserts, updates and deletes and publishes these as messages into camel routes.
As a producer, can save or update documents into couch.
Can support as many endpoints as required, eg for multiple databases across multiple instances.
Ability to have events trigger for only deletes, only inserts/updates or all (default).
Headers set for sequenceId, document revision, document id, and HTTP method type.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-couchdb</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>
