Description Tim Rozet 2021-11-12 16:46:34 UTC
Description of problem:
ovn-kube level driven service controller is sending extra operations for the same service. This can impact scale/performance. 


Version-Release number of selected component (if applicable):
4.9

How reproducible:
Always

Steps to Reproduce:
1. Create a service
2. Check in the ovnkube-master logs for more than 1 OVN transaction

Actual results:
In 4.9 we still use nbctl, so you will see something like:

^ 3 ovn-nbctl transactions


Expected results:
A single ovn-nbctl transaction
