Introduce MetaProtocol Proxy: A Layer-7 Proxy Framework Powered by Envoy
summary
A Layer‑7 proxy framework built on Envoy that turns protocol specifics into metadata key‑value pairs and uses a simple codec interface (decoder/encoder) to add per‑request load balancing, routing via xDS, rate limiting, circuit breakers, fault injection, mirroring and observability. It ships codecs for 10+ protocols including dubbo, swift and brpc and supports private protocols, shows request‑level LB and mirroring in the demo, and is used in 2022 Olympic online streaming services; latency depends on codec efficiency.
