Sep 1, 2025

Month: 2025-09 — Focused feature delivery in cloudfoundry/routing-release to improve routing scalability and resilience. Implemented hash-based load balancing for Gorouter, introducing a new registration message protocol and the necessary config/message handling changes to support the algorithm. This work lays the groundwork for improved traffic distribution, cleaner endpoint management, and more predictable performance under load. No significant bugs reported this month; main value comes from the capability to route based on headers and balance factors and the corresponding registration flow that keeps endpoints in sync with the hashing strategy. Commitment highlights include the change to registration message types in the Hash-Based Load Balancing feature (#509) with commit f507c68b16e56f4e05da5734aab47a0334429d7b.
