> Components: Table SQL / API, Table SQL / Planner, Table SQL / Runtime

> The Broadcast State Pattern has been requested multiple times to make PTFs
> fully production ready. Users would like to control the behavior of a PTF
> during runtime via kind of a control or rule input. Adopt the concept of
> broadcast state into ProcessTableFunctions by integrating it into the
> existing signature and semantics. Note that this is clearly an extension to
> the SQL standard and gives PTFs more Flink-specific flavor. Broadcast state
> is crucial to bridge the gap to DataStream API applications for broadcast
> joining and rule-based logic.
