Subject [jira] [Commented] (HBASE-16765) Improve IncreasingToUpperBoundRegionSplitPolicy
Date Mon, 31 Oct 2016 22:08:59 GMT

Lars Hofhansl commented on HBASE-16765:
---------------------------------------

OK... So I'll check the class into every branch, so that it could optionally be configured
as SplitPolicy. For 2.0 I'm going to make this the default.
Everybody cool with that?

> We just did some experiments on some larger clusters and found that while using IncreasingToUpperBoundRegionSplitPolicy
generally works well and is very convenient, it does tend to produce too many regions.
> Since the logic is - by design - local, checking the number of regions of the table in
question on the local server only, we end with more regions then necessary.
