> Labels: starter
>
> The {{StreamTableEnvironment#explain(Table)}} command for tables of a
> {{StreamTableEnvironment}} only outputs the abstract syntax tree. It would be
> helpful if the {{explain}} method could also generate a string from the
> {{DataStream}} containing a physical execution plan.
