Sorting in a Memory Hierarchy with Flash Memory

摘要

Flash memory continues to improve in price, capacity, reliability, durability, and performance. In addition to consumer and client devices, flash memory is also employed in many servers. Its optimal usage in various classes of server software, including web servers, file-and-print servers, and database servers, requires evaluation and analysis. The present paper analyzes the use of flash memory for database query processing including algorithms that combine flash memory and traditional disk drives.
