Hi APISIX & SkyWalking community I was discussing with Wei Jin about using Prometheus SDK to monitor URI-level metrics of APISIX/OpenResty. Wei received feedback that way of using Prometheus SDK causing a significant performance impact. From the observability perspective, Prom is not good at gathering a large scale of entities' metrics due to its local cache and pull mode. Instead, we should consider providing a push way like Envoy ALS[1] and Metrics Service[2] did(it does through gRPC, and SkyWalking recommended in the prod environment. If this is accepted and agreed by the APISIX community, we could look for implementation in the skywalking-nginx-lua[3] repo to collect metrics(meter in SkyWalking) and use HTTP(in SkyWalking native meter format) to report
