john commented on FLINK-27748: ------------------------------ [~knaufk] Probably not, maxParallelism controls the total concurrency of the job, and we want to control the concurrency of a specific operator. > AdaptiveScheduler should support operator fixed parallelism > ----------------------------------------------------------- > > Key: FLINK-27748 > URL: https://issues.apache.org/jira/browse/FLINK-27748 > Project: Flink > Issue Type: Improvement > Components: Runtime / Task > Reporter: john > Priority: Minor > > In the job topology, if the user specifies the concurrency of the operator, > AdaptiveScheduler should support the operator's maximum parallelism equal to > the user-specified parallelism during the scheduling process. And the minimum > parallelism is equal to the number of slots available to the cluster. > This is especially useful in certain scenarios, > For example, the parallelism of an operator that consumes Kafka is specified > to be equal to the number of partitions. Or you want to control the write > rate of the operator, etc. -- This message was sent by Atlassian Jira (v8.20.10#820010)
