Not sure I understand this comment. This code applies to joins, I believe.

> Local index support to Phoenix
> ------------------------------

> Key: PHOENIX-933
> URL: https://issues.apache.org/jira/browse/PHOENIX-933
> Project: Phoenix
> Issue Type: New Feature
> Reporter: rajeshbabu
>
> Hindex(https://github.com/Huawei-Hadoop/hindex) provides local indexing
> support to HBase. It stores region level index in a separate table, and
> co-locates the user and index table regions with a custom load balancer.
> See http://goo.gl/phkhwC and http://goo.gl/EswlxC for more information.
> This JIRA addresses the local indexing solution integration to phoenix.
