Abstract
The strong momentum of key-value store applications drives the commercialization of key-value-specific hard disk drives. To achieve higher degree of performance, the specific flash-based solid state drives would be also commercialized for key-value store applications in the foreseeable future. However, the existing fixed-sized management strategies of flash-based devices would potentially result in low storage space utilization on managing variable-sized key-value data. This problem inspires this paper to propose a key-value flash translation layer (KVFTL) design to improve the storage space utilization of the key-value-specific solid state drives (KVSSDs). A series of experiments was conducted to evaluated the proposed design, and the experimental results on space utilization and device performance are very encouraging.
