salvalcantara opened a new pull request, #1230:
URL: https://github.com/apache/flink-kubernetes-operator/pull/1230
## What is the purpose of the change
Adds an opt-in autoscaler policy that applies the highest recommended scale
factor within each slot sharing group. By default, the policy only proceeds
when the estimated TaskManager replica count changes.
## Brief change log
- Adds configuration options for the per-slot-sharing-group scaling policy
and its TaskManager replica change requirement:
```yaml
job.autoscaler.scaling.max-scale-factor-per-slot-sharing-group.enabled:
"true"
job.autoscaler.scaling.max-scale-factor-per-slot-sharing-group.taskmanager-replicas-change-required:
"true"
```
- Applies the policy through the existing autoscaler scaling flow
- Documents the new options and behavior
and applies the policy through the existing scaling flow.
