Point of the talk: To teach developers how to design highly parallelized data enrichment workers that fetch external API data or microservice context without hitting rate limits or blocking downstream consumers.

Duration: 45 Minutes

Detailed Breakdown: Data enrichment often requires stitching incoming telemetry with external user profiles, geocoding APIs, or CRM data. Doing this synchronously destroys pipeline throughput. This talk covers how to build non-blocking enrichment workers using FastStream and Asyncio. We will explore advanced throttling strategies, token-bucket algorithms for API compliance, and how to use Redis as a high-speed caching layer to prevent redundant external network requests. Attendees will walk away with a resilient blueprint for handling thousands of requests per second.
