PAX-Based Join Processing for Flash Memory
Lee, Jae-Uk, Tae‐Sun Chung · ASME Press eBooks · 2011
Flash memory has many advantages over hard disk. Such as smaller size, lower power consumption, shock resistance and fast random access speed. It has been gradually edged out traditional storage systems. Especially, with the advantage of random read operation, a welltuned DBMS (Database Management System) is able to be created over flash memory storage systems. The traditional implementation of database techniques on these storage systems does not works as well as that on hard disks. In this paper, we describe the PAX-based layout's advantage over flash memory, and we propose a PAX Join algorithm to take advantage of PAX- based layout to reduce total data transferred and thereby improve performance for join processing.
