发明名称 Wait-free parallel data cache
摘要 A system and method for managing a data cache in a central processing unit (CPU) of a database system. A method executed by a system includes the processing steps of adding an ID of a page p into a page holder queue of the data cache, executing a memory barrier store-load operation on the CPU, and looking-up page p in the data cache based on the ID of the page p in the page holder queue. The method further includes the steps of, if page p is found, accessing the page p from the data cache, and adding the ID of the page p into a least-recently-used queue.
