Jeremy Hanna commented on CASSANDRA-952:
----------------------------------------
Jonathan - Also it looks like you're doing the datacenter replication factor
per keyspace now, which is what we're hoping to have for multi-tenants.
However, in StorageService, I was under the impression that the replication
strategy is handled as though it was per keyspace but in reality it is a quasi
singleton. So all keyspaces will share the same RS of that type. Is that not
true now? I didn't see any change to that in your patches. Just wanted to
make sure that doesn't cause odd problems - if all of the keyspaces are sharing
the same DatacenterShardStrategy instance which is only meant for one of those
keyspaces.

> Currently DCQuorum is broken in trunk, Suggesting the following fix...
> Write to DC's
> 1) Move determineBlockFor(int expandedTargets, ConsistencyLevel
> consistency_level) to AbstractEndpointSnitch
> 2) Add the same to support DC Quorum in DatacenterShardStategy
> Read to DC's
> 1) find suitable nodes was a list which was returning a list of local DC's
> earlier but now it is just one node and MD is been sent by other nodes. Need
> to have an option to even avoid MD from other DC's?
