> This JIRA to improve performance of multiple scanners running on a same
> region in parallel. The scenarios where we will get the performance benefits:
> * New TableInputFormat with input splits smaller than HBase Region.
> * Scanning during compaction (Compaction scanner and application scanner over
> the same Region).
