GitHub rebuilt their push processing system to handle code pushes more efficiently by transitioning from a single, monolithic job to a decoupled architecture using Apache Kafka. This update improved scalability, fault isolation, and development ease, while addressing previous issues with retries, blast radius, and latency. The new system led to significant reliability and performance improvements, including a decrease in pull request sync time by 33% and increased the push processing success rate to 99.999%.
