Messaging & Event Streaming

📨 Messaging & Event Streaming

Master the tools and patterns used to build decoupled, asynchronous, and event-driven architectures.

🏗️ The Messaging Roadmap

Phase 1: Foundations

  • Focus: Message Queues vs. Event Streams, Pub/Sub, and Point-to-Point.
  • Goal: Understand the “Why” behind asynchronous communication.

Phase 2: Message Brokers

  • Focus: RabbitMQ, Exchange types (Direct, Fanout, Topic), and Acknowledgments.
  • Goal: Build reliable task-based communication channels.

Phase 3: High-Throughput Streaming

  • Focus: Apache Kafka, Partitions, Consumer Groups, and Retention policies.
  • Goal: Handle millions of events per second with strict ordering guarantees.

🛠️ Key Concepts

  • At-least-once vs. Exactly-once: Navigating delivery guarantees.
  • Backpressure: Managing producers that are faster than consumers.
  • Dead Letter Queues (DLQ): Handling poison messages gracefully.
