Dynamic configuration of redis Parameters Based on Java

Many users are familiar with redis list, hash, set, string, and other operations,

This section briefly introduces the dynamic parameter modification, master-slave switchover, persistent settings, and system information monitoring.

The redis Chinese document provides detailed instructions on console operations,

The following content is the Java API application.

Package redis; import Java. util. list; import Java. util.

Select (1 );}}

There is a way to reset the system parameters. After testing, it is useless, so it is not written.

The select method has not been used. If you have used it, you can follow the instructions to introduce it ~
