[jira] [Created] (CALCITE-575) Calcite: Project Removal to consider optional field names

Laljo John Pullokkaran created CALCITE-575:
----------------------------------------------

             Summary: Calcite: Project Removal to consider optional field names
                 Key: CALCITE-575
                 URL: https://issues.apache.org/jira/browse/CALCITE-575
             Project: Calcite
          Issue Type: Bug
            Reporter: Laljo John Pullokkaran
            Assignee: Laljo John Pullokkaran


Calcite-92 seems to have changed behavior of ProjectRemoveRule to discard field names while considering if a project is trivial. Unfortunately they way Hive is integrated with Calcite we would need to preserve names.

This issue would go away once Calcite Operators get converted to Hive Operators as opposed to Hive AST.
