Abstract
Methods, systems, and computer storage media for providing temporary storage for data that has to be durably stored based on a replica set that includes a partial replica and a set of full replicas in a distributed computing environment. The partial replica of the replica set temporarily and durably stores data but does not persist the data when the set of full replicas have communicated a promise response to store the data. In operation, instructions to communicate promise responses are communicated to a replica set comprising a partial replica and a set of full replicas. A promise response indicates that a replica in the replica set will commit the data block of the write request. Promise responses are received from the set of full replicas. Based on receiving promise responses from the set of full replicas, a forget instruction is communicated to the partial replica to forget the data block.
