Thank you for investigating that! From what I can tell, the pruning for hash lookups is done via [`KeyRangeBitmapPruningExpr`](https://github.com/apache/datafusion/blob/b6f6990ed5f926fd04fe04c46410f8c6ddfb7674/datafusion/pruning/src/key_range_bitmap_expr.rs#L33). Maybe if we can extend the existing hash lookup expression and we can support `HashTableLookupExpr::pruning_bitmap` for multiple partitions, the existing pruning implementation "comes for free". -- This is an automated message from the Apache Git Service.
