Implementing Raft Protocol with Project Loom - GeeCON 2022

Explore the implementation of the Raft consensus protocol using Project Loom in this GeeCON 2022 conference talk. Dive into the world of distributed systems and learn about one of the most challenging problems: consensus. Discover how Raft is utilized in popular systems like etcd, Kubernetes, Consul, Kafka, and Hazelcast. Gain insights into the protocol's asynchronous communication between cluster nodes, including leader election, log replication, and node failure tolerance. Examine the basics of Raft and witness practical code examples demonstrating how to implement protocol behavior using Project Loom's promising features. Topics covered include consensus algorithms, Hazelcast CP Subsystem, Replicated State Machine, algorithm characteristics, leader election, heartbeats and replication, node state transitions, structured concurrency, and potential applications of Project Loom in Hazelcast.
