    Description

      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:

      1. Must be flushless. Coordinated memstore flushes across a cluster are bad.
      2. 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.
