-watchers and multiple notifications
Gopala Krishna Gundeboyin... 2012-11-29, 11:26
I am trying to understand the behavior of watches and need clarification on
Documentation says (
"*Be prepared to handle the case where the znode changes multiple times
between getting the event and setting the watch again. (You may not care,
but at least realize it may happen.)*"
1. Does this mean, once I set the watch again I am guaranteed to receive
one notification for all multiple events that I missed in the mean time
immediately? Or do I get a notification only when there is a new event?
2. Let say I got an event, before start handling the event I set the watch
again and got busy in the callback. Meanwhile I have multiple events. Are
these events result into one notification or multiple notifications?
In my system, I don't want to miss a notification at the same time I want
to handle an event just once if there are multiple notifications triggered
Thanks in Advance!
