README

        
The CP Subsystem module of Hazelcast IMDG 3.12 offers linearizable and

distributed implementations of the Java concurrency primitives; `Lock`,

`Semaphore`,`CountDownLatch`, `AtomicReference`, and `AtomicLong`. This repo

contains a couple of code samples to demonstrate how to use them for

distributed coordination use cases. 

We use a simple deployment model in the use-cases. We deploy a cluster of 3

Hazelcast servers with the CP Subsystem enabled. The cluster works like 

a central distributed coordination service. Then, we connect to the Hazelcast

cluster via multiple Hazelcast clients.

Each use-case is implemented as a Maven submodule, except the `server` 

submodule, which contains common utilities for the use-cases. We also provide

a set of scripts to start and terminate Hazelcast servers and clients. Last,

each use-case creates multiple Hazelcast server and client instances, but all

of their logs are printed into a single `log.txt` file in the project root

directory to help you track the progress easily.  

Make sure to hit `mvn clean install` in the project root directory before

running the code samples.
