• Do we need to perform datastore update in Validation Orchestrator?
  https://github.com/openBackhaul/ControllerDomainManager/blob/develop/spec/Functions/Validation/ValidationOrchestrator.md#:~:text=ValidationOrchestrator%20would%20overwrite%20the%20RunningDS%20with%20the%20content%20of%20the%20CandidateDS

• Rollback of CandidateDS is required if response != 204 or it can be handled while processing next request?
  https://github.com/openBackhaul/ControllerDomainManager/tree/develop/spec/Functions/Interpretation

• Can we have a case where we need to restore StartupDS to RunningDS? like hardware reboot, controller restart, factory reset, etc.

• Can we respond with 429 only if CandidateDS is in locked state? Will support response for list-* and provide-* which are using RunningDS.
  https://github.com/openBackhaul/ControllerDomainManager/blob/2f1cab5cc53e4ce783295ed976d8194da114a551/spec/Functions/Validation/ValidationOrchestrator.md#:~:text=During%20the%20process%20of%20interpretation%20and%20validation%2C%20the%20CDM%20does%20not%20accept%20requests%20to%20any%20of%20the%20InterpretationFunctions%20and%20responds%20429%20%27too%20many%20requests%27.

• Should we explicitly validate RPC before copying from CandidateDS to RunningDS?

• What is the purpose of performing reconstruction, construction and destruction of various function names.

1. Like in Application Template, we are performing measure-management-domain-interface-function-name and reconstruct-management-domain-interfaces-function-name
2. LoadBalancer Template, measure-load-balancer-function-name, construct-forwarding-function-name, destruct-forwarding-function-name, reconstruct-forwarding-function-name
3. Controller Template, measure-controller-function-name, reconstruct-mount-point-function-name, destruct-mount-point-function-name
