Facebook kisses DRAM goodbye, builds memcached for flash â€“ Old GigaOm
Q:Â What do you get when you mix Facebookâ€™s (s fb) extensive memcached usage with its strategy of â€œcold storageâ€ for infrequently accessed data? A: McDipper, a Facebook-built implementation of the popular memcached key-value store designed to run on flash memory rather than pricier DRAM. Memcached, for the unfamiliar, is an open-source key-value store that caches frequently accessed data in memory
