Amitanand Aiyer commented on HBASE-4346:
----------------------------------------
This task is a nice-to-have. Not really required for addressing the
"correctness" issue with 2856.
Will work on this as the next step. Putting a place holder here.
> 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.
> Reporter: Amitanand Aiyer
> Priority: Minor
> Fix For: 0.94.0
