> The TableAPI does not forward the idleness configuration from a DataStream
> source. That can lead to the halt of processing if all sources are idle
> because {{WatermarkAssignerOperator}} [1] will never set a channel to active
> again. The only way to mitigate the problem is to explicitly configure the
> idleness for table sources via {{table.exec.source.idle-timeout}}.
> Configuring this value is actually not easy because creating a
> {{StreamExecutionEnvironment}} via {{create(StreamExecutionEnvironment,
> TableConfig)}} is deprecated.
