Re: [Zookeeper-user] zookeeper vs. heartbeat messages

Hi Stefan, If I understand your question correctly, you can use the SEQUENCE flag when creating child nodes. To identify the last one added, just check which child has the largest sequence value. This queue example in wiki tutorial works similarly, although in the queue example we are interested in the oldest child.

Yeah - I just hit this point and I'm getting a little confused what  
exactly a watch is.
I thought having one ZkClient that implements watcher and with each  
notification simply re subscribe notifications with for example  
exists(path, true) would solve this one notification problem.
But looks like I need to create a new ZooKeeper object after each  
notification? Is that right?

Thanks a lot,
Stefan
