Subject [jira] [Commented] (HBASE-15556) need extensible ConsistencyControl interface
Date Thu, 31 Mar 2016 17:36:25 GMT

Sean Busbey commented on HBASE-15556:
-------------------------------------

Please have initial patches target the master branch. All changes go there first, unless they
are somehow only applicable to earlier branches.

Also, please start a discussion on dev@ about this change (including what the target use case
is) before putting much more work into this. The MVCC is pretty central to the operations
of HBase, so I'm not sure how amenable to making it pluggable we are.

> The class MultiVersionConsistencyControl should be abstracted into an interface ConsistencyControl
so it can be extended by a configured custom implementation class, with MultiVersionConsistencyControl
as the default.
