Deduplication of metadata in storage systems
The patent US12032537B2 outlines a method for deduplicating metadata within a storage system. The process begins with receiving an indication to deduplicate metadata stored in a first data structure. The method involves identifying two groups of chunk identifiers linked to distinct content identifier structures of two metadata elements. These identifiers represent data chunks, and the method seeks to find a common sequence of chunk identifiers that is associated with subsets of these data chunks. Once identified, the method updates the first data structure to reference a common sequence identifier, which consolidates the representation of the identified subsets, thereby optimizing the storage of metadata.
Additionally, the claims detail various aspects of the deduplication process, including the determination of chunk identifiers based on object identifiers and offset ranges, as well as the potential for the metadata elements to be associated with the same or different objects. The method also includes mechanisms for creating new data chunks corresponding to the common sequence and updating the data structure accordingly. Furthermore, it allows for the adjustment of thresholds based on available storage resources, ensuring efficient management of metadata. The patent also encompasses a computer program product and a system that implements these methods, highlighting the integration of processor and memory components to facilitate the deduplication process.
