Patrick Hunt commented on ZOOKEEPER-555:

I continue to be impressed by the power of just the few primitives/guarantees 
that we provide.

That said,I consider my solution a bit of a hack (not necessarily bad, just not 
optimal), really 
Arni's solution is the correct one, we should provide the ability to get the 
stat as part of the 
get_children. However this (stat) won't be generally available till 3.3 even 
assuming Arni completes
it (please!) and this other alternative might be a good enough solution in the 
mean time.

>         Attachments: getchildren_stat.patch
> GetChildren() is the only non-create/delete API which does not include the 
> node stat information. I propose that the definition of GetChildren() should 
> be:
>     class GetChildrenResponse {
>         vector<ustring> children;
>         org.apache.zookeeper.data.Stat stat;
>     }
> There is a trivial fix to the server (FinalRequestProcessor.java): rsp = new 
> GetChildrenResponse(children, stat);
> And something similar to the  client library.
