Fast key-value stores: An idea whose time has come and gone

Remote, in-memory key-value (RInK) stores such as Memcached and Redis are widely used in industry and are an active area of academic research. Instead, data center services should be built using stateful application servers or custom in-memory stores with domain-specific APIs, which offer higher performance than RInKs at lower cost. In this paper, we evaluate the potential performance improvements of stateful designs, propose a new abstraction, the linked, in-memory key-value (LInK) store, to enable developers to easily implement stateful services, and discuss areas for future research.
