Redis

With the persistence feature, Redis guarantees that there will be no loss (or small loss) of data even if the server is restarted. However, because the data is stored on a single server, if the server's hard disk fails, it can also cause data loss.

Redis 4.0. Version 0.0 has started chargingRedis 4.0.5.0 has been charged for completionThere was a ServiceStack.Redis.RedisNativeClient approach to changing the Redis version today "get_db" did not solve the problem for a long timeStill no problem

I. Introduction of RedisRedis is a key-value storage system. Similar to memcached, but solves the situation where the data is completely lost after a power outage, and she supports more untyped value types, in addition to string, supports lists

Problems encountered in traditional mysql+ memcached architecturesThe actual MySQL is suitable for massive data storage, through the memcached to load hot data to the cache, speed up access, many companies have used such a structure, but with the
