-------------------------------------
I'm at an off-site today. I'll take a look tomorrow.
> Improving optimization using Materialized Views [CALCITE-786] by allowing
> strings and predicates that specify ranges.

> Key: CALCITE-925
> URL: https://issues.apache.org/jira/browse/CALCITE-925
> Project: Calcite
> Issue Type: Improvement
> Reporter: Amogh Margoor
> Assignee: Julian Hyde
> Priority: Minor
>
> This is in continuation of CALCITE-786 where queries are optimized using
> materialized views. Earlier we were not supporting predicates that were
> specifying ranges over a variable, for e.g., x < 90 and x > 30. No we would
> be able to optimize even when such predicates are used either in query or to
> specify a view.
> Also adding support for strings for the same optimization.
