We are also considering a range optimization on hash join, on queries like
```sql
SELECT ...
FROM left, right
WHERE left.x > right.y AND
left.x + left.y < right.x + 10 AND
left.z = left.x
```
and it paves the way for a streaming execution of the `HashJoinExec`. We’d
like to collaborate on this PR. I guess a google doc would be the perfect
medium to share ideas @isidentical.
