  • Data operations using a cache table in a file system
    Patent number: 11144505
    Abstract: Methods, systems, and computer storage media for providing reduced-latency data operations in a file system. In operation, a request to perform a data operation associated with a B+ table storage of a file system is received. The file system supports the B+ table storage that is accessible using a B+ tree lookup logic for accessing B+ table data and supports a cache storage that is accessible using a cache table lookup logic for accessing cache data in the cache storage. A number of references to the location in the B+ table storage is determined. The location in the B+ table storage is associated with the request to perform the data operation. Based on determining the number of references to the location, a cache storage location to perform the data operation is accessed. The cache storage location is mapped (using the cache table) to the location in the B+ table storage.
