Till Rohrmann created FLINK-22254: ------------------------------------- Summary: Only trigger scale up if the resources have stabilized Key: FLINK-22254 URL: https://issues.apache.org/jira/browse/FLINK-22254 Project: Flink Issue Type: Improvement Components: Runtime / Coordination Affects Versions: 1.13.0 Reporter: Till Rohrmann Fix For: 1.14.0
In order to improve the scale up behaviour of the {{AdaptiveScheduler}} we should only trigger a scale up operation if the resource set has stabilized. That way it should be possible to immediately restart the job after its cancellation if the resource set has not changed in the meantime. One way to implement this behaviour is to only notify the {{State}} about new resources after they have stabilized. -- This message was sent by Atlassian Jira (v8.3.4#803005)
