Subject [jira] [Commented] (HBASE-13512) Region granularity data keys
Date Mon, 20 Apr 2015 18:49:59 GMT

Andrew Purtell commented on HBASE-13512:
----------------------------------------

This is pretty easy to achieve. We'd only vary the policy for assigning data keys to HFiles
from strictly by CF metadata to by region metadata, possibly with data keys for the region
stored in meta.

> Currently we can only set data keys at column family granularity. Consider support for
setting data keys per region. Then tenant specific data keys in a multitenant table becomes
possible, provided all keys for a tenant can fit exclusively within a region boundary, assisted
by a tenant key aware split policy.
