> 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).
> Some JIRAs related to this one:
