[jira] [Created] (SPARK-52160) Dynamic pruning not being used with broadcast hash join

John Smith created SPARK-52160:
----------------------------------

             Summary: Dynamic pruning not being used with broadcast hash join
                 Key: SPARK-52160
                 URL: https://issues.apache.org/jira/browse/SPARK-52160
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.5.5
            Reporter: John Smith


We have a hive partitioned dataset, partitioned on year, month, day. When doing a broadcast hash join with that table, with the partition keys as the join keys, dynamic partition pruning is not being used. It's reading all partitions. The query would be a lot faster with DPP. 

 

When filtering on year, month, and day (no join), Spark does read only the partitions that match the filter.
