Flavio Paiva Junqueira commented on ZOOKEEPER-43:
-------------------------------------------------
This is an interesting new feature. If I understand correctly this patch, a
client resets its watches upon reconnection if its session is renewed. The main
idea is to make reconnection transparent to the client, since with the current
code a client has to reset its watches manually.
Resetting the watches does not make it fully transparent, though, as there
might have been events between the time the client was disconnected and the
time its watches have been reset. I wonder how big of a deal this is for
ZooKeeper applications.
Because some applications might prefer not to have this feature on due to
backward compatibility or because of potential missed events, it might be a
good idea to provide a "switch" that applications can use to turn this feature
on and off.
