-----------------------------------------

             Summary: HBase snapshots v2
                 Key: HBASE-14413
                 URL: https://issues.apache.org/jira/browse/HBASE-14413
             Project: HBase
          Issue Type: New Feature
            Reporter: Vladimir Rodionov
             Fix For: 2.0.0


We need new implementation of snapshot feature that is more robust and performant.  Ideally,
it will work with multiple tables as well. The possible areas of improvements:

#  Must be flushless. Coordinated memstore flushes across a cluster are bad.
#  Verification phase must be distributed, done in parallel and not on Master.

In theory, the only info we need to record snapshot of a table: list of WAL files, list of
HFiles and max sequence id of an edit which has been flushed per Region.
