----------------------------------
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.
