Rui Fan created FLINK-34743: ------------------------------- Summary: Memory tuning takes effect even if the parallelism isn't changed Key: FLINK-34743 URL: https://issues.apache.org/jira/browse/FLINK-34743 Project: Flink Issue Type: Improvement Components: Autoscaler Reporter: Rui Fan Assignee: Rui Fan Fix For: kubernetes-operator-1.9.0
Currently, the memory tuning related logic is only called when the parallelism is changed. See ScalingExecutor#scaleResource to get more details. It's better to let the memory tuning takes effect even if the parallelism isn't changed. For example, one flink job runs with desired parallelisms, but it wastes memory. -- This message was sent by Atlassian Jira (v8.20.10#820010)
