[GitHub] [apisix] Nobilta opened a new issue, #7862: help request: Can i use etcd's gRPC proxy as apisix's etcd?
Nobilta opened a new issue, #7862:
URL: https://github.com/apache/apisix/issues/7862
### Description
i know that apisix's watch is based on http/1.1,so if i have many route or upstream,apisix will make lots of post request to etcd(such as this paper:https://apisix.apache.org/zh/blog/2021/08/10/apisix-nginx/#%E5%9F%BA%E4%BA%8E-etcd-watch-%E6%9C%BA%E5%88%B6%E7%9A%84%E9%85%8D%E7%BD%AE%E5%90%8C%E6%AD%A5%E6%96%B9%E6%A1%88)
so can i use etcd's gRPC proxy(https://etcd.io/docs/v3.5/op-guide/grpc_proxy/) to coalesce watch and improve my performance?if it can be use,why i have some errors in logs,and how can i to fix it ?(i make sure etcd is work,i can use client to control etcd cluster)

@tokers fine,but if i want to decrease watch numbers(because my etcd cluster is high load),what should i do?modify the config_etcd.lua's syncdata function?

That would be error prone. We are releasing the apisix 3.0 which will use gRPC to communicate with etcd.

No, you cannot (at least for now). The ETCD proxy is just a transparent proxy and you still have to use the gRPC protocol from APISIX, which has not been supported yet.
