CFDC: a flash-aware replacement policy for database buffer management

Flash disks are becoming an important alternative to conventional magnetic disks. Although accessed through the same interface by applications, flash disks have some distinguished characteristics that make it necessary to reconsider the design of the software to leverage their performance potential. This paper addresses this problem at the buffer management layer of database systems and proposes a flashaware replacement policy that significantly improves and outperforms one of the previous proposals in this area.
