xds-relay: Performance initiatives for control plane management
summary
xds-relay is a lightweight caching and aggregation proxy that removes connection and serialization hotspots by maintaining a single gRPC stream per cache key, fanning out one upstream snapshot to many sidecars; demo shows two Envoy clients share one upstream stream and cached snapshots every 10s. It runs close to clients, serves staging traffic at Lyft, handles thousands of xDS clients, targets CPU reduction, and plans features like endpoint subsetting and state-of-the-world to Delta xDS conversion.
