stack resolved HBASE-6613. -------------------------- Resolution: Duplicate Resolving in favor of the work over in HBASE-13103 > Automatically merge empty regions > --------------------------------- > > Key: HBASE-6613 > URL: https://issues.apache.org/jira/browse/HBASE-6613 > Project: HBase > Issue Type: New Feature > Components: master, regionserver, util > Affects Versions: 0.94.1 > Reporter: Ionut Ignatescu > > Consider an usecase where row keys has an increasing value(time-series data > for example) and data retention is set to a concrete value(60 days for > example). > After a period of time, longer than retention, empty regions will appear. > This will cause high memory use on region servers. > In my opinion, regions merge could be part of major compaction or another > tool should be provided. From my understading, it is possible to merge 2 > empty regions without make table offline, but it's not possible to merge one > empty region with a non-empty region without close/unassing this regions. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
