Abstract:Flash-based key-value (KV) caching has received increasing attention in recent years with the advantages of flash-based solid state drives (SSDs) in capacity and cost. By caching most data in SSD, the caching system can eliminate lots of time-consuming requests to back-end data stores to provide low-latency services. To adapt to the unique technical constraints of flash memory, flash-based KV caching adopts a slab-based log-structured management scheme in which the slab is the basic storage unit, and uses a sm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
