Can upstream backends be modified dynamically, just like https://github.com/weibocom/nginx-upsync-module, via lua api?

agentzh commented

BTW, it's recommended to use the balancer_by_lua* feature of ngx_lua for such requirements. It is much more flexible and can handle an unlimited number of possible backend servers at finest granularity:

@agentzh But balancer_by_lua* cannot be used to unhardcode server itself, can it? The example under your link hardcodes server and uses the lua block for all things other than server.
