It's true, the requirements of this issue have evolved quite a bit and we
should adapt the JIRA issue for that ;-)
+1 for creating an issue to support arbitrary inner joins with a single row
input and addressing that issue with this PR.
Once that issue is resolved, we can revisit FLINK-4541 and see what's left
to do.
@AlexanderShoshin, can you open the JIRA issue and adapt this PR to it?
