> 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.
