Re: Zookeeper 3.3.4 guarantees across sessions from the same client ?
Hi Neha, Your proposal seems fine to me. When we close a session in PrepRequestProcessor, we line up all ephemerals of the session to be deleted, so as long as the create comes after those deletes, I don't see a problem with checking if the session is closing. Do you want to create a jira so that we can work on it and perhaps other can comment as well? -Flavio On Aug 1, 2013, at 7:02 PM, wrote: > Hi Neha, > > I'm assuming that the Unless we expire a session and delete ephemerals > atomically, there are only two options I see: > > 1- Delete right before expiring the session > 2- Delete right after expiring the session > > Because of timing, we can have the following.
