Vishal Kathuria commented on ZOOKEEPER-646:
-------------------------------------------
@Alexander - is there a separate Jira for the MountRemoteZookeeper? This is
exactly what we need for our scenario.
We aren't worried about the update throughput at the moment. Our case is that
we have quite a few ensembles that are created based on availability/throughput
needs of different pieces of data. For example, data that needs to survive a
region failure is stored in a global ensemble, but data that doesn't is stored
in a regional ensemble.
For a client, it shouldn't have to make connections to multiple ensembles to
get the data that they are interested in. So a client connects to a nearby
ensemble, which has mounted the data tree (ideally a subset) of other ensembles.
