Heart Rate Mechanism in Java

Question

Do you know if there is a well-designed (based on state machines) heartbeat mechanism written in Java as an open source project? In fact, for me it is not necessary. I just assume that this kind of design covers various cases of fault tolerance.

After searching on Google, I found the Java DMK. Your answers will be useful for me to avoid testing all such projects in order to find the best one.

Answer 1

I could point you to the JGroups project. It has a decentralized system that has a cluster state and has functionality initially.

There is also the famous ZooKeeper project, which also has some of your needs.

Hope this helps.
