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
