    Abstract: A data manager may include a data opaque interface configured to provide, to an arbitrarily selected page-oriented access method, interface access to page data storage that includes latch-free access to the page data storage. In another aspect, a swap operation may be initiated, of a portion of a first page in cache layer storage to a location in secondary storage, based on initiating a prepending of a partial swap delta record to a page state associated with the first page, the partial swap delta record including a main memory address indicating a storage location of a flush delta record that indicates a location in secondary storage of a missing part of the first page. In another aspect, a page manager may initiate a flush operation of a first page in cache layer storage to a location in secondary storage, based on atomic operations with flush delta records.

    Abstract translation: 数据管理器可以包括数据不透明接口,被配置为向任意选择的面向页面的访问方法提供对包括对页面数据存储器的无闩锁访问的页面数据存储的接口访问。 在另一方面,可以基于发起部分交换增量记录的前缀到与第一页相关联的页面状态,将高速缓存层存储器中的第一页面的一部分的交换操作发起到辅助存储器中的位置, 该部分交换增量记录包括指示闪存增量记录的存储位置的主存储器地址,其指示第一页的缺失部分的辅助存储器中的位置。 在另一方面,页面管理器可以基于具有刷新三角洲记录的原子操作来启动高速缓存层存储器中的第一页面的刷新操作到辅助存储器中的位置。
