- * To be able to prune partitions on a join key, the filtering side needs to
- * meet the following requirements:
- * (1) it can not be a stream
- * (2) it needs to contain a selective predicate used for filtering
Review comment:
Base on another case
https://github.com/apache/spark/pull/34070#issuecomment-973893038. May be we
