  • Cache optimization technique for large working data sets
    Patent number: 9501420
    Abstract: A system and method for recognizing data access patterns in large data sets and for preloading a cache based on the recognized patterns is provided. In some embodiments, the method includes receiving a data transaction directed to an address space and recording the data transaction in a first set of counters and in a second set of counters. The first set of counters divides the address space into address ranges of a first size, whereas the second set of counters divides the address space into address ranges of a second size that is different from the first size. One of a storage device or a cache thereof is selected to service the data transaction based on the first set of counters, and data is preloaded into the cache based on the second set of counters.
