描述

From discussion in https://github.com/envoyproxy/envoy/pull/8231#discussion_r324191998

Key take aways:

Prefer using version_info instead comparing new xDS delivered config with existing one, this also solves https://github.com/envoyproxy/envoy/issues/7676
Add a UUID in ConfigSource for deduplication, instead of hashing ConfigSource proto to automatically dedup. This means RDS/SDS ConfigSource sent from LDS should be deduplicated at control plane.

貢獻者指南

研究方向: 研究 Envoy 中目前如何實現 xDS 去重，理解問題中提出的 version info 和 UUID 方法，並提出實作計畫。
