Devoxx Greece 2025 - Async Excellence: Unlocking Scalability with Kafka by Natan Silnitsky

How do you scale 4,000 microservices while tackling latency, bottlenecks, and fault tolerance? At Wix, Kafka powers our event-driven architecture with practical patterns that enhance scalability and developer velocity.
This talk explores four key patterns for asynchronous programming:

Integration Events: Reduce latency by pre-fetching instead of synchronous calls.
Task Queue: Streamline workflows by offloading non-critical tasks.
Task Scheduler: Enable precise, scalable scheduling for delayed or recurring tasks.
Iterator: Handle long-running jobs in chunks for resilience and scalability.

Learn how to balance benefits and trade-offs, with actionable insights to optimize your own microservices architecture using these proven patterns.
