Perhaps we should clarify what you mean by "client" (..would ping..). If you mean the ZK client library, then that would make sense - rather than use a static list of servers, each time it was disconnected it would refresh it's list and pick one. I took it to mean the client application (using the ZK library). The issue is that the client application has no way to tell the ZK client lib to use a different list of servers, other than a complete teardown of the ZK object & session, which I'm trying to avoid. > > Hasn't come up before, but yes I agree it's a useful feature. Ok, thanks. We don't have a specific ETA to implement it, I just wanted to explore the option a bit before we finalized some aspects of our design. Should we do the work I'll submit matches for the Java and C client. -Dave
