Latest Patents

One of Kumaran Nagappan's latest patents involves the innovative concept of metadata compaction. This technique provides a method for compacting indirect blocks, which are crucial in efficiently storing and retrieving data. In essence, an object is represented through a structure that includes both data blocks, containing the object's actual data, and indirect blocks that comprise the block numbers indicating where the corresponding data blocks are located in storage. By compacting block numbers within a set of indirect blocks, Kumaran's invention leads to the creation of a compacted indirect block. This block contains a base block number, a count of additional block numbers following the base block, and a specific pattern of these block numbers. By storing the compacted indirect blocks in memory, his approach allows for quicker access operations to the object, improving the overall performance as the block numbers are read directly from memory rather than being loaded from disk.
