Change Data Capture with Debezium reads PostgreSQL WAL logs and MySQL binlogs to stream every insert, update, and delete to Kafka in real time. This guide covers connector configuration, schema evolution, exactly-once delivery, and production operational patterns.
Design and implement event-driven systems with Node.js and TypeScript using EventEmitter, RabbitMQ, and Kafka. Covers pub/sub patterns, event schema design, and production resilience. For backend engineers building decoupled, scalable services.
Implement CQRS (Command Query Responsibility Segregation) to scale reads independently from writes. Learn command bus patterns, query bus patterns, eventual consistency, projections, CQRS without event sourcing, testing strategies, and when the complexity is justified.
Decouple services and handle long-running operations with event-driven architecture, using CloudEvents and Kafka for reliable, observable event flows.
Scale Kubernetes workloads based on queue depth, Kafka lag, cron schedules, and custom metrics. Master KEDA architecture, combine with HPA, and optimize for cold starts and production reliability.
Build reliable webhook systems with HMAC-SHA256 signatures, idempotency keys, exponential backoff, dead-letter queues, and production testing patterns.
