    Description

      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).
