    Abstract: Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for managing checkpoints associated with the caches, where the checkpoints are used to determine the position at which to begin processing recovery logs in the event of a failure.

    Abstract translation: 提供了用于管理具有多个高速缓存的系统中的高速缓存的技术，其可以包含相同数据项的不同副本。 具体地说，提供了用于协调对这些数据项执行的写盘操作的技术，以确保数据项的较早版本不会被写入较新的版本，并且减少在故障之后恢复所需的处理量。 提供了各种方法，其中使用主机与多个高速缓存进行协调以使数据项被写入持久存储器。 还提供了用于管理与高速缓存相关联的检查点的技术，其中检查点用于确定在发生故障的情况下开始处理恢复日志的位置。

    Abstract: Caches on nodes in a cluster are globally managed so that a data item may be retained in any of the caches. A replacement policy that governs the replacement of data items stored in the caches selects buffers for replacement according to factors that include the state of the caches of other nodes. Some cached data items are designated as globally shared and assigned a primary cache. If a buffer holds a copy of a data item whose primary cache is another node, then the data item in the buffer is favored for replacement over a local data item or a global data item for which this is the primary cache. Cache retention values of buffers on different nodes may be compared. The buffer with the lowest cache retention value is selected for replacement. The replacement policy may also account for the way other caches in the cluster are configured.
