Misty Stanley-Jones updated HBASE-11120:
----------------------------------------
Attachment: HBASE-11120.patch
This is my attempt to understand and explain the new compaction algorithms. I
think I have probably missed some bits and misconstrued some bits. Please
provide feedback and corrections as necessary. I have left the old algorithm
explanation in place and just re-labeled it as "prior to 0.96.x".

> [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
