Explore Event Sourcing and CQRS implementation using Akka and Java in this 49-minute conference talk from Devoxx. Dive into the motivations behind and architecture of ES & CQRS, focusing on their application in microservices and distributed systems. Examine an example implementation using Akka's actor-based toolkit, covering topics such as Akka Persistence, cluster singletons, and cluster sharding. Learn about the decomposition of monolithic systems, both in code and data, and understand how these strategies can be applied to build loosely coupled microservices. Follow along with code examples in Java, explore key concepts like actors and message extractors, and witness a practical demonstration of these principles in action.
