Hi all, I'm totally new to Flink and I got a question about Flink's slot sharing feature. Suppose I have a pipeline like *Mapper-> Reducer, *and of cause the operators are* not *chained to a single task. When the job is actually scheduled to the Flink cluster, there is a Mapper task and a Reducer task scheduled to the same TaskManager's slot, here slot sharing works.
The question is: the slot sharing is an abstract concept, sharing slot doesn't means sharing thread, is that right? The Mapper task and Reducer task are still launched in independent threads. Thanks in advance. Thanks, Huafeng
