Abstract: Systems and methods include determination of a first logical page number of a first database page to be persisted, identification of a first blockmap page associated with the first logical page number, determination, from the first blockmap page, of a block number associated with the first logical page number, determination that the block number is an object key, determination, in response to the determination, that the block number is an object key, determination of a first object key to associate with the first logical page number, and writing of the first database page to the object store using the first object key.

Abstract: Disclosed herein are system, method, and computer program product embodiments for disaster resilience of applications managed by Kubernetes operators. An embodiment operates by creating an orchestration and worker cluster, where the worker cluster is coupled to the orchestration cluster by a proxy server. Custom resources are deployed to the orchestration cluster and custom resource controllers are deployed to the worker cluster. The proxy server federates these custom resources between the orchestration cluster and the worker cluster. During disasters, the worker cluster is recreated and reconciled to prevent loss of the federated cluster.
