stack commented on HBASE-7055:
------------------------------

Please edit the release note and remove this sentence "A tier based compaction 
algorithm has been developed."

I would be interested in when this new compaction should be used in place of 
what we have (both as prospective user and as an hbase dev) and how it relates 
to what we have currently.

[~sershe] On 'Most of the patch (e.g. CompactionManager) is refactoring of the 
compaction code out of (H)Store, so the code as such as old, except for the 
alternative CompactionManager.' <-- This sounds good.
                
> port HBASE-6371 tier-based compaction from 0.89-fb to trunk
