. Although it has good stability, it faces the increasing number of users and massive data volumes, high concurrency and other problems are hard to cope. So in the past one or two years, many open-source teams and Technology enthusiasts have admired the "nosql" technology ). Anyone who knows a little about the computer knows that memory read/write is definitely much more efficient than disk I/O operations. But with memcached, can we abandon the traditional "Relational Database" completely? Of co
