> In CALCITE-7031, we introduce a new join type: LEFT MARK, and left a TODO
> about implementing the LEFT MARK JOIN in the enumerable convention.
> An LEFT MARK JOIN will keep all rows from the left side and creates a new
> attribute to mark a tuple as having join partners from right side or not.
> LEFT MARK JOIN is typically generated by rewriting SOME/EXISTS/IN subqueries.
> This ticket will add support for the LEFT MARK type to the hash join.
