Benjamin Reed commented on ZOOKEEPER-646:
-----------------------------------------
i think there are some rather fundamental problems with the
MountRemoteZooKeeper proposal: to maintain semantics you have to dig into the
core functionality, remote failures cause pipeline stalls, and we have found
that in practice when you do such partitioning you don't need ordering
guarantees across partitions. if you do give up on ordering across partitions,
you avoid introducing further complications in the pipeline and you also get
nice scalability of the writes.
