Description

Submarine currently use limit to control resources in CRD.

resources:
  limits:
    cpu: '1'
    memory: 512M

Hope to suggest changing the [ limits ] to [ requests to limits ]. e.g.

resources:
  limits:
    cpu: '1'
    memory: 512M
  request:
    cpu: 0.5
    memory: 100M

This is a more rigorous resource description. Otherwise, the operator will lock all resource limits and requests in [cpu: '1'] and [memory: 512M] in pod.
When adding a notebook, if the resources limits are large but the actual execution python process resources are small, the resource utilization is not high.
