-------------------------------
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.
