Part of #7955. My goal here is to lay the groundwork for pushing down joins. I am only implementing bounds pushdown because I am sure that is cheap and it will probably be quite effective in many cases. And it will be ~ easy to push down a reference to the whole hash table in a followup PR. Another followup that can be done is to enable parent filter pushdown through HashJoinExec. Similar to FilterExec this requires adjusting parent filters for the join's projection, but we also need to check what columns each filter refers to to push it into the correct child (or not push it if it refers to columns from both children and can't be disjoint). -- This is an automated message from the Apache Git Service.
