-------------------------------------

             Summary: Document the need to backport FLINK-30213 for using autoscaler with older version Flinks
                 Key: FLINK-32868
                 URL: https://issues.apache.org/jira/browse/FLINK-32868
             Project: Flink
          Issue Type: Improvement
          Components: Autoscaler
            Reporter: Zhanghao Chen


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.
