Subject [jira] [Commented] (HBASE-7875) introduce a compaction switch in HBase Shell
Date Wed, 27 Mar 2013 18:37:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13615611#comment-13615611
] 

Sergey Shelukhin commented on HBASE-7875:
-----------------------------------------

+0 on feature - if it makes sense as global config setting it could be added as a config setting
and it should work for both table and column family implicitly (will have to be asked of the
store, not region, though).
+1 on patch
