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