First Redis must be more advanced and better used than memcached, because Redis is a new technology, and the following is the ability of Redis and memcached not.

Redis has and memcached can implement cache servers (one cache server is deployed separately)

1, Redis not only supports simple k/v type of data, but also provides the storage of data structures such as list,hash,set,zset,sorted.

2, Redis support data backup, that is, Master-slave mode of data backup.

3, Redis support data persistence, can keep the in-memory data on the disk, restart can be loaded again for use, memcached is cached in memory, reboot after the cache disappears.

4, Redis is a single-threaded dynamic allocation of memory, memcached is multithreaded is fixed pre-allocated memory, not flexible.
