I want to use couchbase to store java objects for fast access and reuse in a java compute node.
The couchbase client opens one connection to the server and is thread safe, but they don't have any connection pooling.
It works great until the open file limit is exceeded if I don't do a client.shutdown(), but if I put in the client.shutdown() before ending the java compute node I don't get the too many files open exception but my performance goes way down.
One suggestion was to put the client in a singleton class, so there is only ever one client since it is thread safe, but they are running in a java application daemon...not sure if that will work in broker JCN.
Will it?

| You could put your own pool of connections into a singleton. |

Volume testing to be sure, but the singleton pattern for the client seems to work.
