I went through the explanation on MaxParallelism in the official docs here: https://ci.apache.org/projects/flink/flink-docs-master/ops/production_ready.html#set-maximum-parallelism-for-operators-explicitly
However, I am not able to figure out how Flink decides the parallelism value. For instance, if I setMaxParallelism to 3, I see that for my job, there is only 1 subtask that is created. How did Flink decide that 1 subtask was enough? Regards, James
