> Create Physical Execution Plan of a DataStream
> ----------------------------------------------
>
> Key: FLINK-4623
> URL: https://issues.apache.org/jira/browse/FLINK-4623
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Anton Solovev
> 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.
