      Description

      Sub-region provides a light weight management below region level.
      Matt Corgan has a nice summary of the relationship between region size and number of regions on region server:
      https://issues.apache.org/jira/browse/HBASE-7667?focusedCommentId=13575024&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13575024

      HBASE-7667 proposed stripe compaction. However, to fully achieve fine-grained management, more components should participate:

      • memstore flush should ideally have knowledge about what makes stripe compaction work efficiently
      • we need to figure out where to store sub-region boundary information so that components have easy access. Boundary information should sustain after region moves from one server to another.

      Since HBASE-7667 focuses on compaction aspect, this JIRA discusses sub-region management in other components so that we better understand the benefits and complexities.
