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.
