James Taylor commented on PHOENIX-1434:
---------------------------------------
In the prior version, splits were slowed down so much by the scan occurring to
update stats that we didn't really get that far since writes were so
problematic. Take a look at the code and see if you see any holes.
[~mujtaba] has identified what looks to be a fairly easily reproducer of the
issue.
> Stats are not maintained correctly through splits and/or compactions

> We're seeing the number of regions the stats table thinks there are not being
> in agreement with the actual number of regions. It seems to be related to
> splits and compactions. In particular, when a split is occurring, the
> deletion of the stats for the region being split is not being deleted as
> expected.
