> [14:20:38]  <jdcryans>	 seems that there's http://hbase.apache.org/book.html#compaction
and http://hbase.apache.org/book.html#managed.compactions
> [14:20:56]  <jdcryans>	 the latter doesn't say much, except that you should manage
them
> [14:21:44]  <jdcryans>	 the former gives a good description of the _old_ selection
algo
> [14:45:25]  <jdcryans>	 this is the new selection algo since C5 / 0.96.0: https://issues.apache.org/jira/browse/HBASE-7842
