Christopher Tubbs commented on ZOOKEEPER-4968:
----------------------------------------------
For my application, I created a wrapper ZooSession object that wraps ZooKeeper
and handles replacing the ZooKeeper object internally when it experiences a
session expiration, since the ZooKeeper client object is typically useless
after a session expiration. However, I only implemented a subset of ZooKeeper's
methods, to proxy, because I only used a few. It would be great to have an
interface for ZooKeeper that defined the client API. Then I could have my own
wrapper object implement that interface, so my automatic-reconnecting client
could be used anywhere the usual ZooKeeper client object is used, as a drop-in
replacement.
