HI, I would create a river between ES and CouchDB using a view created with CouchDB. i know it's possible with a CouchDB filter. Is it possible ? SuperGlu ---

I had thought about this feature, but then it is not required. - A couchdb view is a way of querying data (say by using a map function) - A view can be easily replicated by a similar query in Elasticsearch. So, there is no need to replicate a view inside Elasticsearch. > Is it possible ? Technically it is tough to do, because CouchDB does not expose a \_changes interface for views (IIRC). Also, I think the functionality can easily be achieved now. Regards, Mahendra [http://twitter.com/mahendra](http://twitter.com/mahendra) ---
