The Assembly to use

Function description

You can cache the entity classes directly, set the expiration time, remove the cache, and get the cache functionality.

Use the Redisclientfactory factory to obtain a Redis client instance. If Redis has a password set, add the modifications in the configuration file

            Client = Factory. Createredisclient (Configmanager.redisserver, configmanager.redisport);            Client. Password = configmanager.redispwd;

Modify the Redis IP and port number, and then the password.

Usage Scenarios

In the specific use of the process, the use of redis time-out can be some persistent management of data, for some data consistency is not high data cache, so that the read speed, the use of Redis cluster can be a master-slave replication function, Redis cluster has no central node, and with replication and failover characteristics , which prevents a single node from becoming a performance bottleneck, or because a node is offline and the entire cluster is offline.
