Ted Yu created HBASE-7857:
-----------------------------
Summary: Sub-region management
Key: HBASE-7857
URL: https://issues.apache.org/jira/browse/HBASE-7857
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
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
Since HBASE-7667 focuses on compaction aspect, this JIRA discusses sub-region
management in other components.
User may want to see how sub-regions are shaped on web UI.
