--------------------------------------

             Summary: Local index region pruning is not working as expected.
                 Key: PHOENIX-5096
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5096
             Project: Phoenix
          Issue Type: Bug
            Reporter: Lars Hofhansl


The pruning of local indexes should do the following:
* Use the local index
* Reduce the number of regions based on filters on the table's primary (i.e. WHERE conditions
including prefixes of the primary key)

Instead it looks like in order for this to work the needed PK column need to be included in
the local index itself, changing the sort order of the local index.

I'll provide some examples in the comments.
