Andrew Purtell commented on HBASE-1728:
---------------------------------------
@Jim: A byte would probably suffice. That said, the value is just a HCD
attribute and also a value in some policy table. We wouldn't be tagging kvs
with 32 bits as part of the replication stream. The policy mechanism is within
the replicator. Either it forwards a kv to a peer or does not. So the width of
this value has no impact on performance.

> Support column family scoping via a new HCD attribute. Add convenience
> methods. Add Thrift, REST, and Stargate support. Provide initial set of
> scoping constants and javadoc setting expectations for a simple default
> binary scoping policy: replicate, or do not. Make the underlying type Integer
> so more complex edit routing policies are possible.
