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 16):
A non-transitory computer-readable medium storing computer-executable instructions that, when executed by a processor, cause the processor to perform operations comprising:\n receiving a first request associated with a first entry in a cache, the cache including a plurality of storage nodes and a plurality of entries; receiving a second request associated with a second entry in the cache; in response to the first request:\n determining that an associative array associates the first entry with a first storage node; \n causing a first thread to obtain exclusive control of a first entry lock, the first entry lock controlling access to the first entry; \n causing the first thread to modify the associative array to dissociate the first entry from the first storage node; and \n causing the first thread to release exclusive control of the first entry lock; and \n in response to the second request:\n determining that the associative array associates the second entry with a second storage node; \n causing a second thread to obtain exclusive control of an second entry lock, the second entry lock controlling exclusive access to the second entry; \n causing the second thread to modify the associative array to dissociate the second entry from the second storage node; and \n causing the second thread to release exclusive control of the second entry lock, wherein the first thread has exclusive control of the first entry lock and the second thread has exclusive control of the second entry lock at least partially concurrently.
