[jira] [Created] (HIVE-25851) Replace HiveRelMdPredicate with RelMdPredicate from Calcite

Alessandro Solimando created HIVE-25851:
-------------------------------------------

             Summary: Replace HiveRelMdPredicate with RelMdPredicate from Calcite
                 Key: HIVE-25851
                 URL: https://issues.apache.org/jira/browse/HIVE-25851
             Project: Hive
          Issue Type: Improvement
          Components: CBO
    Affects Versions: 4.0.0
            Reporter: Alessandro Solimando


`HiveRelMdPredicates` was copied from `RelMdPredicates` in Calcite long ago, it has few differences which could be ported to the Calcite version, if needed.

The goal of the ticket is to:
# ascertain which are the additional features in `HiveRelMdPredicates`, port them to Calcite if needed
# drop `HiveRelMdPredicates` in favour of `RelMdPredicates` in order to benefit from all the advances in such class
