>
> Flink does not natively support outer joins at the moment.
> This issue proposes to implement a sort-merge outer join algorithm that can
> cover left, right, and full outer joins.
> The implementation can be based on the regular sort-merge join iterator
> ({{ReusingMergeMatchIterator}} and {{NonReusingMergeMatchIterator}}, see also
> {{MatchDriver}} class)
> The Reusing and NonReusing variants differ in whether object instances are
> reused or new objects are created. I would start with the NonReusing variant
> which is safer from a user's point of view and should also be easier to
> implement.
