@spacewander I am new to apisix, and I test this function follow your tips using test-nginx。 I have following points to discuss 1. the key of hash_on can be defined as “vars_combinations”, refers to http://nginx.org/en/docs/stream/ngx_stream_upstream_module.html ``` The key can contain text, variables, and their combinations (1.11.2) ``` 2. In upstreams.lua， should I check the schema in this situation？ I think it is no need to do this， because it is an advance feature ``` local function get_chash_key_schema(hash_on) if not hash_on then return nil, "hash_on is nil" end if hash_on == "vars" then return core.schema.upstream_hash_vars_schema end if hash_on == "header" or hash_on == "cookie" then return core.schema.upstream_hash_header_schema end if hash_on == "consumer" then return nil, nil end return nil, "invalid hash_on type " .. hash_on end ``` 3. If all vals are not exist， for example ``` $request_uri-$host ``` the hash on should be "-", and will not use default chash_key "remote_addr"， is it acceptable？ Refer to https://trac.nginx.org/nginx/ticket/765， any plan to support map？ ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
