This is not used anymore, right?
I think we should remove it.
> Improve perfomance of inner joins with a single row input
> ---------------------------------------------------------
>
> Key: FLINK-5159
> URL: https://issues.apache.org/jira/browse/FLINK-5159
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Reporter: Alexander Shoshin
> Assignee: Alexander Shoshin
> Priority: Minor
>
> All inner joins (including a cross join) can be implemented as a
> {{MapFunction}} if one of their inputs is a single row. This row can be
> passed to a {{MapFunction}} as a {{BroadcastSet}}.
> This approach is going to be more lightweight than the other current
> strategies.
