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:
Maven users will need to add the following dependency to their pom.xml for this component:
Where hostname is the hostname of the running couchdb instance. Port is optional and if not specified then defaults to 5984.
The following headers are set on exchanges during message transport.
Headers are set by the consumer once the message is received. The producer will also set the headers for downstream processors once the insert/update has taken place. Any headers set prior to the producer are ignored. That means for example, if you set CouchDbId as a header, it will not be used as the id for insertion, the id of the document will still be used.
The component will use the message body as the document to be inserted. If the body is an instance of String, then it will be marshalled into a GSON object before insert. This means that the string must be valid JSON or the insert / update will fail. If the body is an instance of a com.google.gson.JsonElement then it will be inserted as is. Otherwise the producer will throw an exception of unsupported body type.
For example if you wish to consume all inserts, updates and deletes from a CouchDB instance running locally, on port 9999 then you could use the following:
If you were only interested in deletes, then you could use the following
If you wanted to insert a message as a document, then the body of the exchange is used
