Subject Re: Why Would Accumulo v1.4.1 Run Major Compaction on a One Tablet Table?
Date Fri, 01 Feb 2013 21:15:20 GMT
There is no direct correlation. A tablet will minor compact multiple times
as data is added. Once the files cross a certain size threshold, a split is
initiated. Once the number of files for a tablet crosses a certain numeric
threshold, a major compaction occurs.
