Abstract
Improved caching mechanisms are presented herein for use with an in-memory distributed cache and, potentially, other types of caches. One mechanism permits cache clients to wait on a cache key being fetched by one or more other cache clients. When the cache key arrives at the cache, the waiting cache clients may be called back with the cache key. Another mechanism allows a service to push changed values directly into a distributed cache. Yet another mechanism allows the storage of information in a cache that defines dependencies between cached values. The dependency information can be utilized to invalidate cache values that are dependent upon other cached values that have been invalidated.
