> @imjoey One thing confuses me that the labels field is attached on the whole `upstream` object, It's closer to the labels on Kubernetes Service, not the Pod, and labels on Pod are more pragmatic, so what about attaching labels for each node in this upstream, with this support, we can group the nodes by labels, and in turn implementing some features like blue green release, canary release or other route rules. Your idea is great, But we also need to pay attention to the structure of APISIX, 1. The `nodes` under `upstream` is not an object yet; 2. Blue-green or canary releases are more tied to business, not suitable for writing in upstream objects, but more suitable for extension in plug-ins, But upstream currently does not provide any plug-in implementation; if we add labels in nodes, I think it will be a big change. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
