Coherence Playground

Introduction

This repository contains my own personal Coherence related projects/demos mostly related to managing and monitoring Coherence.

Note: These projects don't necessarily reflect the recommended 'Production' way of setting and running various Coherence bits and pieces, but are a good starting point for playing with and trying things out with Coherence. They are for educational purposes only. For the official way/ best practises of doing setting up Coherence, please refer to the official Coherence commercial documentation.

Requirements

To get the best out of these projects, you should have the following minimum requirements:

• JDK 17
• Maven 3.8.x
• Installed the latest Coherence CLI - Install instructions

Some examples require docker and docker-compose.

Important: If you find any problems with these projects or see something that needs to be changed or clarified, please submit an issue.
