Distributed Cache System

摘要

Various embodiments of the present disclosure provide improved systems and techniques for intelligently allocating cache requests to caches based upon the nature of the cache objects associated with the cache requests, and/or the condition of the caches in the distributed cache system, to facilitate cache system utilization and performance. In some embodiments, an allocation of cache requests may be performed in response to detection of a problem at one of a group of cache servers. For example, in some embodiments, a particular cache server may be entered into a safe mode of operations when the cache's ability to service cache requests is impaired. In other embodiments, an allocation of cache requests may be performed based on an cache object data type associated with the cache requests.

1. A method for intelligently allocating cache requests among caches in a distributed cache system, the method comprising:
allocating, at a computing device, a cache request to a first cache of the distributed cache system in response to detection of a problem at one of the other caches in the distributed cache system, or based on a data type associated with a cache object associated with the cache request; monitoring the caches in the distributed cache system; when a slowdown in service is detected at a first cache, switching the first cache to a safe cache mode of operation; periodically performing a test to determine whether the first cache has resumed normal operations; when the first cache has resumed normal operations, switching the first cache to a normal cache mode of operations.
