Lars Hofhansl commented on PHOENIX-5096:
----------------------------------------
Tests pass... Why am I not surprised. There's actually not a single test that
tests whether we get the right number of regions for local indexes. Sigh.
-v2 adds a simple test.
> Local index region pruning is not working as expected.

> 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 key
> (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.
