Review comment:
In fact, it is 2 instances of the same service. In docker-compose, the 2 service instances are started with the same namespace, group and service name, but have different exposed ports, which is equivalent to different instances of the same service registered to nacos.
docker-compose:
https://github.com/apache/apisix/blob/48398d3f1501fe425b08673609605ea9d8039f54/ci/pod/docker-compose.yml#L230-L263
these 2 service instances on nacos-dashboard:
Before de-duplication, the number of APISIX fetches to these two services is 6:
https://github.com/apache/apisix/runs/5180101415?check_suite_focus=true
6 = 2 instances * ( in route + in service + in upstream )
