> Key: FLINK-32868

> Project: Flink
> Issue Type: Improvement
> Components: Autoscaler
> Reporter: Zhanghao Chen
> Assignee: Zhanghao Chen
> Priority: Minor
> Labels: pull-request-available
>
> The current Autoscaler doc states on job requirements as the following:
> Job requirements:
> * The autoscaler currently only works with the latest [Flink
> 1.17|https://hub.docker.com/_/flink] or after backporting the following fixes
> to your 1.15/1.16 Flink image
> ** [Job vertex parallelism
> overrides|https://github.com/apache/flink/commit/23ce2281a0bb4047c64def9af7ddd5f19d88e2a9]
> (must have)
> ** [Support timespan for busyTime
> metrics|https://github.com/apache/flink/commit/a7fdab8b23cddf568fa32ee7eb804d7c3eb23a35]
> (good to have)
> However, https://issues.apache.org/jira/browse/FLINK-30213 is also crucial
> and need to be backported to 1.15/1.16 to enable autoscaling. We should add
> it to the doc as well, and marked as must have.
