Subject A question about sequential order consistency that zookeeper garantees
Date Thu, 23 Oct 2014 03:15:49 GMT
Hi,Zookeepers,

I'd like to ask a question about sequential order consistency that zookeeper garantees.

Say, 2 zookeeper clients want to update the same znode data one after the other.Client1 sends
the request 1 second before Client2.
What would be the end result? There is no order gurantee here, dure to network delay, it is
likely that clients1 send the request before client2, but the zookeeper servers first execute
the request from Client1 before client2

If this is not what sequential order consistency means, then what exactly does sequential
order consistencymeans, what does zookeeper exactly garantee?

Thanks.
