Subject [jira] [Commented] (ACCUMULO-1011) automatically merge away small tablets
Date Fri, 18 Oct 2013 13:45:42 GMT

Ryan Leary commented on ACCUMULO-1011:
--------------------------------------

I think the last proposal seems reasonable except I think user created tablets should be _by
default_ marked ineligible, but not precluded from being eligible for an automatic merge.
If you are pre-splitting a table that is arranged by date, for instance, and also performing
age-off, you will eventually have a large number of empty tablets.

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