ABSTRACT:
An object cache stores objects in a cyclic buffer to provide highly efficient creation of cache entries. The cache efficiently manages storage of a large number of small objects because the cache does not write objects into a file system as individual files, rather the cache utilizes cyclical buffers in which to store objects as they are added to the cache. Because of the use of a cyclic buffer, the high-overhead process of purging cache entries never needs to be performed. Cache entries are automatically purged as they are overwritten when the cyclic buffer becomes full and the input pointer wraps around from the end of a cyclic buffer to the beginning of a cyclic buffer. Additionally, in the event of a system crash or disk subsystem malfunction, inspect and repair time is independent of the size of the cache, as opposed to conventional file systems in which the time is proportional to the size of the file system.
