What's the difference between create and createOrReplace?Whether if the RC existed it will replace it?

@yangjinlogic : Hi, as per current implementation create just does a POST request to APIServer. createOrReplace also does POST but it has a fallback approach of doing a PUT in case 409 is received in the initial POST request. We are discussing to refactor createOrReplace(#2454 ) to behave more like kubectl apply(which ignores updates when there is no modification as compared to previous applied resource). Would appreciate it if you could share feedback on that.

Yes

...behave more like kubectl apply(which ignores updates when there is no modification as compared to previous applied resource)...

If the applicable resource was created previously using kubectl apply (The resource contains an annotation kubectl.kubernetes.io/last-applied-configuration with a JSON representation of the originally applied resource)
