Zusammenfassung:Efficient deduplication for storage systems is disclosed, including: using the current data structure to track a set of deduplication data entries associated with a collection group; determining a flush criterion has been met; and storing the set of deduplication data entries of the current data structure as one or more persistent objects associated with the collection group in a persistent storage, wherein the one or more persistent objects are usable to update a set of persistently stored metadata associated with the collection group that tracks deduplication data entries generated before a previous merge operation.
