Data operations using a cache table in a file system

One or more computer storage media having computer-executable instructions embodied thereon that, when executed, by one or more processors, cause the one or more processors to perform a method for providing data operations in file systems, the method comprising:

• receiving a request to perform a data operation associated with a B+ table storage of a file system, wherein the file system supports the B+ table storage that is accessible using a B+ tree lookup logic for accessing the B+ table data in the B+ table storage, wherein the file system supports a cache storage that is accessible using a lookup logic of a cache table for access cache data in the cache storage;
• determining a number references to a location in the B+ table storage based on a reference count tracker, wherein the location in the B+ table storage is associated with the request to perform the data operation;
• and
• based on the number of references to the location, accessing a cache storage location to perform the data operation, wherein based on the cache table, the cache storage location is mapped to the location in the B+ table storage, wherein the cache table supports indirect access to the B+ table storage comprising B+ table data stored in known locations in the B+ table storage, the B+ table data is temporarily stored in corresponding cache storage locations.

A computer-implemented method for providing data operations in file systems, the method comprising:

• determining a number references to a location in the B+ table storage based on a reference count tracker, wherein the location in the B+ table storage is associated with the request to perform the data operation;
• and
• based on the number of references to the location, accessing a cache storage location to perform the data operation, wherein based on the cache table, the cache storage location is mapped to the location in the B+ table storage, wherein the cache table supports indirect access to the B+ table storage comprising B+ table data stored in known locations in the B+ table storage, the B+ table data is temporarily stored in corresponding cache storage locations.
