[jira] [Created] (BEAM-9075) Join re-ordering doesn't work for ZetaSQL

Brian Hulette created BEAM-9075:
-----------------------------------

             Summary: Join re-ordering doesn't work for ZetaSQL
                 Key: BEAM-9075
                 URL: https://issues.apache.org/jira/browse/BEAM-9075
             Project: Beam
          Issue Type: Bug
          Components: dsl-sql-zetasql
    Affects Versions: 2.17.0
            Reporter: Brian Hulette
            Assignee: Brian Hulette


Join re-ordering can actually break queries in the ZetaSQL planner because Calcite's JoinCommuteRule doesn't work when schemas have nested fields. It only adjusts RexInputRef nodes and not RexFieldAccess.
