Rui Fan created FLINK-35814: ------------------------------- Summary: Don't scale up continuously when the throughout cannot be increased after scaling up Key: FLINK-35814 URL: https://issues.apache.org/jira/browse/FLINK-35814 Project: Flink Issue Type: Improvement Components: Autoscaler Reporter: Rui Fan Assignee: Rui Fan
h2. Motivation Currently, the parallelism will be increased continuously when some cases happen. Such as: data skew, bottleneck occurs in other system. In these cases, the throughout(processing rate) cannot be increased even if we increase the parallelism. h2. Solution We don't need to scale up the task continuously when the throughout cannot be increased after scaling up. And it's better to trigger some events to reminder users fix the issue manually. -- This message was sent by Atlassian Jira (v8.20.10#820010)
