摘要：A mechanism is provided in a cache subsystem for cache prefetching based onnon-sequential access. The mechanism determines frequently accessed non-sequentialcache records in the cache subsystem. The mechanism collects trailing record statistics

for the frequently accessed non-sequential cache records. The mechanism determines acaching strategy. The caching strategy comprises prefetching a set of trailing recordsresponsive to a read of a given frequently accessed non-sequential cache record. Themechanism applies the caching strategy to the cache subsystem.
