摘要： Systems and methods for invalidating and regenerating pages. In one embodiment, a method can include detecting content changes in a content database including various objects. The method can include causing an invalidation generator to generate an invalidation based on the modification and communicating the invalidation to a dependency manager. A cache manager can be notified that pages in a cache might be invalidated based on the modification via a page invalidation notice. In one embodiment, a method can include receiving a page invalidation notice and sending a page regeneration request to a page generator. The method can include regenerating the cached page. The method can include forwarding the regenerated page to the cache manager replacing the cached page with the regenerated page. In one embodiment, a method can include invalidating a cached page based on a content modification and regenerating pages which might depend on the modified content.

US08041893B1 System and method for managing large filesystem-based caches 有权

摘要： Embodiments disclosed herein utilize statistical approximations to manage large filesystem-based caches based on imperfect information. When removing entries from a large cache, which may have a million or more entries, the cache manager does not need to find the absolutely oldest entry that has been accessed the least recently. Instead, it suffices to find an entry that is older than most. In embodiments disclosed herein, statistical sampling of the cache is performed to produce models of different properties of the cache, including the number of entries, distribution of access times, distribution of entry sizes, etc. The models are then used to guide decisions that involve those properties. The size of the samples can be adjusted to balance the cost of acquiring the samples against the confidence level of the models produced by the samples. To achieve randomness, entries are stored using prefixes of addresses generated via a message-digest function.
摘要翻译：本文公开的实施例使用统计近似来基于不完美信息来管理大型基于文件系统的高速缓存。从大型缓存中删除条目（可能有百万以上的条目）时，缓存管理器不需要找到最近访问的绝对最旧的条目。相反，只需找到一个比大多数的条目。在本文公开的实施例中，执行高速缓存的统计采样以产生高速缓存的不同属性的模型，包括条目的数量，访问时间的分布，入口大小的分布等。然后，使用模型来指导涉及那些属性。可以调整样品的尺寸以平衡采样的成本与样品产生的模型的置信水平。为了实现随机性，使用通过消息摘要功能生成的地址前缀来存储条目。
