Subject [jira] Commented: (HBASE-938) major compaction period is not checked periodically
Date Wed, 12 Nov 2008 07:33:44 GMT

Billy Pearson commented on HBASE-938:
-------------------------------------

On a small cluster with little data it would not not matter so much but once someone got any
real amount of data I would thank once a day it way to much for a default.
So once a week I thank will be more of the norm as data sets get more data.

> The major compaction period, hbase.hregion.majorcompaction, is not checked periodically.
Currently, we only request major compaction when the region is open or split at which point
we check whether the major compaction period is due.
