      • patchAndCacheStatus

        public void patchAndCacheStatus​(CR resource)
        Update the status of the provided kubernetes resource on the k8s cluster. We use patch together with null resourceVersion to try to guarantee that the status update succeeds even if the underlying resource spec was update in the meantime. This is necessary for the correct operator behavior.
        参数:
        resource - Resource for which status update should be performed

      • updateStatusFromCache

        public void updateStatusFromCache​(CR resource)
        Update the custom resource status based on the in-memory cached to ensure that any status updates that we made previously are always visible in the reconciliation loop. This is required due to our custom status patching logic.

        If the cache doesn't have a status stored, we do no update. This happens when the operator reconciles a resource for the first time after a restart.

        参数:
        resource - Resource for which the status should be updated from the cache

      • removeCachedStatus

        public void removeCachedStatus​(CR resource)
        Remove cached status for Flink resource.
        参数:
        resource - Flink resource.
