ambition commented on FLINK-11039:
----------------------------------
It was originally implemented as RelTimeIndicatorConverter.visit(exchange:
LogicalExchange) function. But this function cannot be used directly in SQL
statements, any distributed engine has Shuffle/Hash/Range/Broadcast operator to
shuffle their data with other deamons in the runtime system. so this function
helps to implement changes to these operations.
