Akka Cluster Quickstart Dashboard - Part 2: Cluster Node Lifecycles

How Akka Cluster Works - Project 1, Part 2/4

Watch on YouTube

Welcome to “How Akka Cluster Works”, a multi-project video series that introduces developers and architects working with Java (and Scala) to the inner workings of Akka Cluster. Project 1 is the Akka Cluster Quickstart Dashboard, and contains four parts. In Part 1: Getting Started, we introduced Akka Cluster using a sample Akka Java project that includes a web dashboard.

In Part 2: Cluster Node Lifecycles, we dive into interacting with nodes in the cluster in real-time. Based on the same sample project, you will learn about Akka cluster node membership lifecycles–including how nodes form themselves into clusters using gossip protocols, and what happens to changes in node member states when we begin to start, stop, and down nodes.

What you’ll learn in this video:

  • A review of the lifecycle of Akka Cluster nodes
  • How do nodes form themselves into a cluster
  • How do nodes leave and join a cluster
  • What happens when nodes are “killed” or become unreachable
