When using the k8s operator in session mode, I understand that we can configure the number of task managers with the

replicas

setting. Is there a possibility to have this scale automatically so that there's always a few spare/idle taskmanagers ready to handle new jobs ?

There is the

autoscaler

for the operator. The example is here.

Thanks but I should have mentioned that my question is for the session cluster. And not about scaling individual jobs but scaling the number of distinct jobs.
