Proposal

Similarly to #3303, it would be nice to provide support for explicitly pausing autoscaling of ScaledObjects at the current replica count so that it no longer scales out/in.

This should be done by applying the autoscaling.keda.sh/is-paused: true annotation on the ScaledObjects resource. When this is the case, the ScaledObject just sticks with the current amount of replicas when it was applied.

Use-Case

Pause autoscaling without having to check how many replicas we run today.

Anything else?

This is in addition to our existing autoscaling.keda.sh/paused-replicas: <replica-amount> which allows you to specify a replica count.

When both annotations are applied, the following logic should be used:

• If autoscaling.keda.sh/paused-replicas is specified, stop autoscaling and puts to given amount
• Otherwise, if autoscaling.keda.sh/is-paused is there, just stop autoscaling and keep it at the current instance count
• Otherwise, keep scaling 🚀🚀🚀

As a workaround, people can use autoscaling.keda.sh/paused-replicas as following:

replicas=$(kubectl get deploy <deployment>  -n <NS> -o=jsonpath='{.status.replicas}') | kubectl annotate scaledObject -n <NS> <scaledObject name>  "autoscaling.keda.sh/paused-replicas=$replicas"
