[Bigdata-developers] zookeeper message delivery guarantees?

[Bryan T. <br...@sy...>]

Hello,

I am wondering if anyone (SeanG?, BrianM?) has looked into the guarantees which zookeeper provides for reliable messaging for operation return codes in the context of ephemeral znode creates.  Basically, I would like to know whether a zookeeper client can rely on observing the return code for a successful operation which creates an ephemeral (or ephemeral sequential) znode -or- have a guarantee that its session was timed out and the ephemeral znode destroyed.  That is, does zookeeper provide guaranteed delivery of the operation return code unless the session is invalidated by a timeout?

Thanks,
Bryan
