That does make sense. I found the [filter_null_join_keys](https://github.com/apache/datafusion/blob/main/datafusion/optimizer/src/filter_null_join_keys.rs) rule which takes care of adding not-null filters to the keys of joins. I thus consider optimizing this case in the hash join a low priority as I expect the improvement to be small. -- This is an automated message from the Apache Git Service.
