Subject [jira] [Commented] (ACCUMULO-1011) automatically merge away small tablets
Date Thu, 31 Jan 2013 01:26:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1011?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13567223#comment-13567223
] 

Eric Newton commented on ACCUMULO-1011:
---------------------------------------

Agreed... something like table.merge.threshold, which would be zero by default.

After your table becomes populated you set it to "100M"  so that old splits can be erased.

This would also make merge-by-size be a parallelizable operation, and not a serialized utility
like it is now.

> Establish a small size configuration parameter, and have the master coordinate a merge
if the tablet size falls below this value.
