摘要： In response to a request including a state object, which can indicate a state of an enumeration of a cache, the enumeration can be continued by using the state object to identify and send cache data. Also, an enumeration of cache units can be performed by traversing a data structure that includes object nodes, which correspond to cache units, and internal nodes. An enumeration state stack can indicate a current state of the enumeration, and can include state nodes that correspond to internal nodes in the data structure. Additionally, a cache index data structure can include a higher level table and a lower level table. The higher level table can have a leaf node pointing to the lower level table, and the lower level table can have a leaf node pointing to one of the cache units. Moreover, the lower level table can be associated with a tag.
摘要翻译：响应于包括可指示高速缓存的枚举状态的状态对象的请求，可以通过使用状态对象来识别和发送高速缓存数据来继续枚举。此外，可以通过遍历包括对应于高速缓存单元的对象节点和内部节点的数据结构来执行缓存单元的枚举。枚举状态堆栈可以指示枚举的当前状态，并且可以包括对应于数据结构中的内部节点的状态节点。此外，缓存索引数据结构可以包括更高级别的表和较低级别的表。较高级别的表可以具有指向低级表的叶节点，并且下级表可以具有指向其中一个高速缓存单元的叶节点。此外，较低级别的表可以与标签相关联。

摘要： A first portion of an identifier can be used to assign the identifier to a slot in a first directory. The identifier can identify a cache unit in a cache. It can be determined whether assignment of the identifier to the slot in the first directory will result in the identifier and one or more other identifiers being assigned to the same slot in the first directory. If so, then the technique can include (1) using a second portion of the identifier to assign the identifier to a slot in a second directory; and (2) assigning the one or more other identifiers to one or more slots in the second directory. In addition, it can be determined whether a directory in a cache lookup data structure includes more than one pointer. If not, then a parent pointer that points to the subject directory can be removed.

摘要： A low priority queue can be configured to list low priority removal candidates to be removed from a cache, with the low priority removal candidates being sorted in an order of priority for removal. A high priority queue can be configured to list high priority removal candidates to be removed from the cache. In response to receiving a request for one or more candidates for removal from the cache, one or more high priority removal candidates from the high priority queue can be returned if the high priority queue lists any high priority removal candidates. If no more high priority removal candidates remain in the high priority queue, then one or more low priority removal candidates from the low priority queue can be returned in the order of priority for removal. Write-only latches can also be used during write operations in a cache lookup data structure.

摘要： A cache region can be created in a cache in response to receiving a cache region creation request from an application. A storage request from the application can identify the cache region and one or more objects to be stored in the cache region. Those objects can be stored in the cache region in response to receiving the storage request.

摘要： Systems and methods that aggregate memory capacity of multiple computers into a single unified cache, via a layering arrangement. Such layering arrangement is scalable to a plurality of machines and includes a data manager component, an object manager component and a distributed object manager component, which can be implemented in a modular fashion. Moreover, the layering arrangement can provide for an explicit cache tier (e.g., cache-aside architecture) that applications are aware about, wherein decision are made explicitly which objects to put/remove in such applications (as opposed to an implicit cache wherein application do not know the existence of the cache.)
摘要翻译：通过分层排列将多台计算机的内存容量集中到一个统一缓存中的系统和方法。这种分层布置可扩展到多个机器，并且包括可以以模块化方式实现的数据管理器组件，对象管理器组件和分布式对象管理器组件。此外，分层布置可以提供应用程序知道的显式高速缓存层（例如，高速缓存替代架构），其中明确地确定在这样的应用中放置/去除哪些对象（与应用程序执行的隐式缓存相反）不知道缓存的存在。）

摘要： Systems and methods that supply a replication layer/agent that is generic to supporting a plurality of storage configuration as part of a distributed store. Such distributed store employs a Common Availability Substrate (CAS) for data transport and consistency, to render the distributed store scalable and available. Such an arrangement enables continuous operation of the store, while the replication subsystem creates new replicas (e.g., for load balancing, failover, and the like).
