Cluster method synchronous execution framework suona

Suona

Suona A decentralized cluster method synchronous execution framework

Git Address ： Poke me

explain

Project reference XXL-job Source code , as well as SpingCloud Service registration for , Realize the method of waking up the rest of the cluster nodes when the single node method is called , To achieve decentralized broadcasting effect

scene

The situation a ： Like in use caffine/ hashMap As the memory cache of the service node , There are drawbacks to this , Because in the cluster , If cache cleanup is required , Cache cleaning is required for each node
Scenario two ： Similar to scenario 1 , Each node of the cluster that needs this service executes a certain method

If you need to solve this kind of solution , should MQ Wait for middleware to realize broadcast operation , So if the middleware hangs , Or what if you don't want to bother to rely on external components ？

that , You can try to use @Suona, It aims to enable developers to call methods on a single node , Trigger the synchronization of other nodes to call , To simulate the operation of broadcasting , And developers Just use an annotation to mark this method , It can be used immediately after unpacking

Usage mode

You just need to use it like this ：

@Service
public class ServiceA {
    @Suona
    public void sayA() {
        // do sth.
    }
}

such , When the method of any node in the cluster is called , Other nodes will also call at the same time

Usage environment

TECHNOLOGY	ENV
JDK	1.8+
SpringCloud	discovery

Be careful

If you use the permission framework or customize web The interceptor needs attention ：
because Suona The trunking communication adopts embedded web interfaces , Therefore, it is necessary to web Request release ： /suona/call
