Description
I have a membase / couchbase cluster running with 3 nodes. I use it to serve images. I moved it to membase for scalability, it easily brings new nodes online, rebalances the data troughout all the nodes.
I noticed 2 things:
- the nginx config does support multiple servers, but only as fallback.
- If you configure a fallback when the key doesn't exists, it requests it from both servers even if the key does exist
I would like to submit a feature request that nginx automatically requests the data at the correct membase shard. More information can be found here: http://www.couchbase.com/develop
Thanks!

Recently introduced hash balancer is compatible with the traditional memcached client hashing (as originally implemented in Cache::Memcached perl module), as well as with at least one known consistent hashing algorithm.
As for automatic couchbase support, there are no plans to implement this as of now.
