Putting the Power of Apache Kafka into the Hands of Data Scientists

Stitch Fix has built a robust data integration platform using Kafka, Flink, and MongoDB to support its machine learning and AI algorithms. The platform is designed to be self-service for Data Scientists, allowing them to easily configure their event data pipelines without requiring direct involvement from the engineering team. The solution leverages Kafka Connect's REST API to build a unified admin API that exposes a simpler API for validation and default parameters. The platform also includes a stream processing engine in Python, which provides a runtime environment with automated monitoring and log collection. The system has been running in production for almost eight months without major outages, freeing up the engineering team to focus on other impactful projects while giving Data Scientists autonomy and freedom.
