Abstract
Systems and methods for utilizing probabilistic data structures to handle interrogations regarding whether or not objects might be stored in an object store of an object storage device are disclosed. More particularly, a controller of an object storage device includes control circuitry and a memory operative to store a probabilistic data structure. The probabilistic data structure has data related to the presence of data in an object store of the object storage device. The control circuitry is configured to receive an interrogation from a computing device for an object; utilize the probabilistic data structure to determine that the object is possibly stored in the object store or definitely not stored in the object store; and in response to a determination that the object is definitely not stored in the object store, respond to the interrogation that the object is not stored in the object store.
