This report provides a detailed overview of a method for building systems that can grow bigger and handle lots of requests. It uses event sourcing with DynamoDB (or ScyllaDB), Kafka, and compares it to REST architecture. The report explains the basic ideas behind event sourcing and how it helps make systems scalable and durable. It also talks about the steps to follow when using event sourcing, like designing the system structure using DynamoDB for storing events and Kafka for sending events around, and setting up Event Store to manage events. The report discusses the benefits of using event sourcing over REST making systems more flexible, and handling complex tasks. It also mentions the importance of replaying events, making sure everything stays consistent, and handling events in real-time. The report ends by talking about the need to test and monitor system performance and make continuous improvements to keep the system scalable. It is a useful guide for researchers who want to use event sourcing with DynamoDB, Kafka, and Event Store to build highly scalable systems.
