Event-Driven Architecture

Overview

Event-driven architecture (EDA) enables loosely coupled, scalable systems by communicating through events rather than direct calls. This skill covers message queues, pub/sub patterns, event sourcing, CQRS, distributed transaction management with sagas, and data streaming with Kafka.
