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

Hi [~huwh]:

Thanks for your comment.

We tried out the autoscaler [autoscaling 
example|https://github.com/apache/flink-kubernetes-operator/blob/main/examples/autoscaling/autoscaling.yaml]
 which is in Application Deployment mode, and it works. But when we tried to 
use session job deployment such as 
[basic-session-job-only.yaml|https://github.com/apache/flink-kubernetes-operator/blob/main/examples/basic-session-job-only.yaml]
 to submit a job to session cluster, we didn't see any autoscale happening.

The autoscaler here is regarding the [FLIP-271: 
Autoscaling|https://cwiki.apache.org/confluence/display/FLINK/FLIP-271%3A+Autoscaling]

> Add Autoscaler support for Session Job

> It would be good to have Autoscaler for Session Jobs.
