Brian Johnson commented on PHOENIX-1561:
----------------------------------------
It would also be cool if it implemented IndexableLoadFunc which would provide
the full range of optimized joins/groups for Pig. I'm working on an
implementation for HBaseStorage, but I'm pretty sure they Phoenix version would
be completely different. I can open up another ticket for it.

> PhoenixHBaseLoader should implement both OrderedLoadFunc and
> CollectableLoadFunc just like HBaseStorage. There is nothing special that
> needs to be done other than implementing a single method. As in HBaseStorage,
> it is up to the user to ensure that the required constraints are not
> violated.

> DelimitedKeyPrefixRegionSplitPolicy
> * if you need a partial key match to be included in the split
> */
