Hi, We are doing about 10K requests/minute on a single haproxy server, we have enough CPUs and memory. Right now each requests looks up a map for backend info. It works well.
Now we need to build some expire logic around the map. Like ignore some entries in the map entries after some time. I could do this in lua, but it woud mean that every request would make a lua call to look up a map value and make a decision. My lua method looks like this: function get_proxy_from_map(txn) local host = txn.http:req_get_headers()["host"][0] local value = proxy_map_v2:lookup(host) if value then local values = split(value, ",") local proxy = values[1] local time = values[2] if os.time() > tonumber(time) then core.Alert("Expired: returning nil: " .. host) return else return proxy end end return end Any suggestions on how this would impact performance, our tests looks ok. Thanks Sachin
