[jira] [Created] (SPARK-29350) Fix BroadcastExchange reuse in Dynamic Partition Pruning

Wei Xue created SPARK-29350:
-------------------------------

             Summary: Fix BroadcastExchange reuse in Dynamic Partition Pruning
                 Key: SPARK-29350
                 URL: https://issues.apache.org/jira/browse/SPARK-29350
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Wei Xue


Dynamic partition pruning filters are added as an in-subquery containing a {{BroadcastExchange}} in a broadcast hash join. To ensure this new {{BroadcastExchange}} can be reused, we need to make the {{ReuseExchange}} rule visit in-subquery nodes.
