Julian Hyde commented on CALCITE-1655:
--------------------------------------

I have reviewed; looks good. I have staged in my https://github.com/julianhyde/calcite/tree/1656-druid-prune branch until the breakage due to CALCITE-1661 is cleared up, then I will commit to master.

> The druid calcite adapter throw an exception when an IN filter is used.
> This happens only in hive because in calcite project the IN filter is transformed to OR automatically. 
> Since this rule does not kick in HIVE and it is better to use the native IN filter from druid instead having huge number of OR clauses i will send a patch that adds the IN filter.
