> StreamExecJoin can consume deletes on key if the join conditions is on
> primary keys. The state lookups happen using the key. However for deletes it
> uses the currently incoming record, which in case of DELETE may be a DELETE
> on key. Given that we have the information about previous value, we can emit
> the full delete instead. This will make JOIN operator work similarly like
> ChangelogNormalize.
