US Patent 12111807 Optimizing storage and retrieval of compressed data

In some examples, a computer system may receive a plurality of chunks of data of a data object. The system may compress the plurality of chunks of data to obtain a plurality of compressed chunks, and may determine whether the plurality of compressed chunks together are less than a threshold size. Based on determining that the plurality of compressed chunks together are less than the threshold size, the system may add, to respective entries in a map data structure, respective sizes of the plurality of compressed chunks. In addition, the system may compact the map data structure by combining values in at least two of the respective entries, and may store the plurality of compressed chunks and the compacted map data structure.
