Julian Hyde commented on CALCITE-1358:
--------------------------------------

How does this relate to CALCITE-1334? See the work that I have already done in https://github.com/julianhyde/calcite/tree/1334-extract-to-range. In particular, see the test cases that work on the EXTRACT function.

> Porting work done in HIVE-14217.
> Logic should split the filter conditions into two parts: those predicates referred to the time dimension, and predicates referred to other columns.
> Then, the predicates on the time dimension should be translated into Druid intervals, possibly consolidating those ranges e.g. to detect overlapping. The other predicates will go into the Druid filter field.
