Hello! I have a quick question about slot-sharing behavior specified at this link ( https://nightlies.apache.org/flink/flink-docs-master/docs/concepts/flink-architecture/). My understanding would be each task slot in Flink cluster represents a sequentially running operator (and therefore can be seen as a thread). But it seems like each operator in Flink is modeled as a thread and many threads can be pinned to the same task slot. For a task slot that contains both task A and task B (thread A and thread B), could these two tasks run in parallel and effectively parallelize tasks assigned to a task slot?
Thanks! Le
