Istvan Toth commented on PHOENIX-6844:
--------------------------------------
It looks like _hbase.increasing.policy.initial.size_ can be tuned per table, so
this may not be that important after all.
> Provide multiple IndexRegionSplitPolicy implementations

>
> We currently inherit IndexRegionSplitPolicy from SteppingSplitPolicy, which
> is the modern HBase default, and provides a good balance between
> parallelization and conserving the number of regions.
> However, users may want to use more or less parallelization for specific
> tables.
> Providing IndexRegionSplitPolicy variants extending
> IncreasingToUpperBoundRegionSplitPolicy and ConstantSizeRegionSplitPolicy
> would enable better tuning of split behaviour for tables with local indexes.
> We should also add a property to specify the default SplitPolicy for when
> adding a local index for the first time.
