Allocating memory resources in a file system based on affinity data

A computerized method comprising:

• receiving, by a processor, file data associated with a file for storage in a data store, the data store comprising at least a large file block cluster that includes one or more small file block clusters, the large file block cluster and the small file block clusters each being associated with an affinity identifier;
• identifying, by the processor, a large file block cluster in the data store based on the affinity identifier, the affinity identifier including an inode address, a file name or a file descriptor;
• selecting, by the processor, a small file block cluster in the identified large file block cluster based on free resources;
• storing, by the processor, the file data in the selected small file block cluster;
• and
• updating, by the processor, affinity metadata of the selected small file block cluster based on storing the file data, thereby associating the data representing the file to a region on the data store.

One or more non-transitory computer storage media having computer-executable instructions that, upon execution by a processor, cause the processor to at least:

• receive file data associated with a file for storage in a data store, the data store comprising at least a large file block cluster that includes one or more small file block clusters, the large file block cluster and the small file block clusters each being associated with an affinity identifier;
• identify a large file block cluster in the data store based on the affinity identifier, the affinity identifier including an inode address, a file name or a file descriptor;
• select a small file block cluster in the identified large file block cluster based on free resources;
• store the file data in the selected small file block cluster;
• and
• update affinity metadata of the selected small file block cluster based on storing the file data, thereby associating the data representing the file to a region on the data store.
