1. A method, comprising, registering a key set, wherein the registering the key set comprises registering a first shared data resource key, the first shared data resource key comprises a first identifier associating a first process executing on a first node with a first shared data resource, and a fourth identifier associating the first node with the first shared data resource, the registering the key set further comprises registering a second shared data resource key, and the second shared data resource key comprises a second identifier associating a second process executing on the first node with a second shared data resource, and a fifth identifier associating the first node with the second shared data resource; and in response to a detection of a failure of the first process, de-registering the first shared data resource key, wherein the second shared data resource key remains registered after the de-registering the first shared data resource key, and wherein the second process continues to operate on the first node after the detection of the failure of the first process; in response to a detection of a failure of the first node, de-registering the first and second shared data resource keys.
