James Taylor commented on PHOENIX-1427:
---------------------------------------
How about rebasing it against the latest and submitting a patch for the 4.0
branch? I think we're good for the 4.2 RC - I got rid of all the key
comparisons and use a bytes ptr for the column family.

> URL: https://issues.apache.org/jira/browse/PHOENIX-1427
> Project: Phoenix
> Issue Type: Bug
> Reporter: Lars Hofhansl

>
>
> I noticed that the StatsCollector does a non-trivial amount of work during
> HBase compactions.
> In a sort of worst case scenario (single node cluster, all data on SSD), it
> adds almost 50% to the compaction time - in a real setup the relative time
> spent there would be much less of course.
