Marshall McMullen commented on ZOOKEEPER-2016:
----------------------------------------------
[~shralex] - I agree this sounds useful but only if it is something we can
opt-in for. Lots of application code which sits on top of the C bindings may
prefer to have more direct control over this than having it automatically
rebalance for them.

> ZOOKEEPER-1355 introduced client-side rebalancing, which is implemented in
> both the C and Java client libraries. However, it requires the client to
> detect a configuration change and call updateServerList with the new
> connection string (see reconfig manual). It may be better if the client just
> indicates that he is interested in this feature when creating a ZK handle and
> we'll detect configuration changes and invoke updateServerList for him
> underneath the hood.
