---------------------------------

             Summary: FlinkRelMdUniqueKeys matches on AbstractCatalogTable instead of CatalogTable
                 Key: FLINK-21361
                 URL: https://issues.apache.org/jira/browse/FLINK-21361
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner
    Affects Versions: 1.12.1, 1.12.0
            Reporter: Ingo Bürk


In FlinkRelMdUniqueKeys there's a match on AbstractCatalogTable rather than the underlying interface CatalogTable. This causes exceptions e.g. during temporal table joins when using alternative catalog table implementations.
