             Summary: Improve join reorder feature without table statistics
                 Key: FLINK-14455
                 URL: https://issues.apache.org/jira/browse/FLINK-14455
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Planner
    Affects Versions: 1.9.0
            Reporter: Leonard Xu


tpc-ds query85.sql run fail when enable TABLE_OPTIMIZER_JOIN_REORDER_ENABLED,and run success
when disable TABLE_OPTIMIZER_JOIN_REORDER_ENABLED.
I analyzed the optimized plan and thought it‘s a bad base for  join reorder feature.
