Hi Yang, One more follow-up question on the custom pod-templates for JobManager and Taskmanager - As you mention pod template is for advanced features so is it that in custom template we just need to include the custom feature like if I want to include a volume mount or sid-car. I don't have to include any flink specific resource, since it is decorated internally, pod will come up with the combined resources - flink + custom.
Let me know if my understanding is correct.
