Worked on enhancing HTTP/2 scalability in the vespa-engine/vespa repository by introducing configurable rate control within the JDisc connector. Developed a new setting, jdisc.http.connector.http2.maxRateControlEvents, to expose Jetty-based WindowRateControl, allowing operators to fine-tune throughput and manage bandwidth usage under high-concurrency workloads. This Java-based backend solution addressed the risk of GOAWAY events during heavy HTTP/2 traffic by enabling precise control over event handling rates. The implementation focused on server configuration and backend development, providing clear semantics for tuning and ensuring more stable service performance for customers running large-scale HTTP/2 workloads in production environments.
