Abstract:
Processes are disclosed for embodiments of a caching system to utilize a snapshot file or other limited size data structure to store a portion of the data stored in a cache. The snapshot file can be stored on persistent or otherwise non-transitory storage so that, even in case of a restart, crash or power loss event, the data stored in the snapshot file persists and can be used by the caching system after starting up. The snapshot file can then be used to restore at least some data into the cache in cases where the cached data in the cache is lost. For example, in cases of a cold-start or restart, the caching system can load data from the snapshot file into the empty cache. This can increase the number of cache hits since the cache is repopulated with useful data at startup.

Claim (Index 1):
A system comprising:\n a data store configured to store an associative array and a plurality of entries, wherein individual entries of the plurality of entries are stored in one or more storage blocks of a plurality of storage blocks, and wherein individual locks of a plurality of locks control access to at least one storage block of the plurality of storage blocks; a first processor configured to:\n obtain control of a shared first group lock and a shared first entry lock, the shared first group lock controlling access to at least a first entry and a second entry, and the shared first entry lock controlling access to the first entry; \n determine that the associative array associates the first entry with a first storage block of the plurality of storage blocks; \n obtain control of an exclusive first entry lock, the exclusive first entry lock controlling exclusive access to the first entry; \n modify the associative array to dissociate the first storage block from the first entry; and \n release control of the exclusive first entry lock; and \n a second processor configured to:\n while the first processor has control of the shared first group lock, obtain control of the shared first group lock and a shared second entry lock, the shared second entry lock controlling access to the second entry; \n determine that the associative array associates the second entry with a second storage block of the plurality of storage blocks; \n obtain an exclusive second entry lock, the exclusive second entry lock controlling exclusive access to the second entry; \n modify the associative array to dissociate the second storage block from the second entry; and \n release the exclusive second entry lock.
