Optimise the storage that we use for storing MVCC information.
--------------------------------------------------------------
Key: HBASE-4346
URL: https://issues.apache.org/jira/browse/HBASE-4346
Project: HBase
Issue Type: Sub-task
Environment: Writing the memstoreTS information is critical to
ensuring Atomic semantics. However, it adds a storage overhead to the disk
files.
This information is useful only when there is a "concurrent" read operation
that needs to ignore a particular key-value.
Once it is known that a key-value is going to be included in all current and
future read operations, MVCC memstoreTS information is
of no use anymore.
We can optimize for storage on disk, by getting rid of these values during
later compactions.
