No, there's no Lua API to access the internal details of a specific
upstream. You're recommended to do the upstream hashing (or sharding
in general) completely in Lua. For example,
local servers = {
{"192.168.1.226", 22133},
{"192.168.1.227", 22133}
}
local server = hash_my_servers(servers, my_key)
local ok, err = memc:connect(server[1], server[2])
where you just need to write a simple hash_my_servers Lua function.
You can use modulo or consistent hashing or any other sharding
algorithm that you like ;)
