Lars Hofhansl commented on PHOENIX-1427:
----------------------------------------
I'll make a simple patch tomorrow.
[~giacomotaylor] says the min/max row keys are no longer needed, so I'll remove
those. A further we can avoid some copying of row and family bytes of the
*every* passed KV.

> Key: PHOENIX-1427
> 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.
