Hi Kurt, Thanks for the reply.
Does this mean that if my job has 3 operators (not chained), it will use at least 3 slots? I thought parallelism was task based. You can define it at an operator level, but that only means that the tasks for that operator are distributed across that many slots. Shouldn't I be able to start the 3 operator job with a parallelism of 1 where all the operators run on the same single slot?
