> Extend Dynamic Partition Pruning Support to DataSources
> -------------------------------------------------------
>
> Key: SPARK-33760
> URL: https://issues.apache.org/jira/browse/SPARK-33760
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.1
> Reporter: Anoop Johnson
> Priority: Major
>
> The implementation of Dynamic Partition Pruning (DPP) in Spark is
> [specific|https://github.com/apache/spark/blob/fb2e3af4b5d92398d57e61b766466cc7efd9d7cb/sql/core/src/main/scala/org/apache/spark/sql/execution/dynamicpruning/PartitionPruning.scala#L59-L64]
> to HadoopFSRelation. As a result, DPP is not triggered for queries that use
> data sources.
> The DataSource v2 readers can expose the partition metadata. Can we use this
> metadata and extend DPP to work on data sources as well?
> Would appreciate thoughts or corner cases we need to handle.
