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

             Summary: Improve DPP for some join type do not support broadcast filtering side
                 Key: SPARK-32855
                 URL: https://issues.apache.org/jira/browse/SPARK-32855
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: Yuming Wang


For some filtering side can not broadcast by join type but can broadcast by size,

then we should not consider reuse broadcast only, for example:

Left outer join and left side very small.
