I see there are 2 answers to 2 different questions around server api limitations
The question and answer seem to indicate that servers can make 1000 api calls per second. This would be ideal for me as my servers can handle up to 4000 concurrent connections.
However, this question and answer seems to indicate the server is limited to making 3 api requests per second. This would not be ideal for me and would take too long to authenticate all new incoming connections and update player statistics. CloudScript was offered as a potential workaround in the previous question with 25 per second, but still doesn't seem ideal.
So I have 3 questions:
What are the official server api and cloudscript call rate limits?
Based on the answer to 1, what is the best way to handle authenticating potentially 4000 session tickets and updating player statistics on potentially 4000 players at a time? Are there any batch apis that servers can call?
Are server apis limited based on ip address or developer secret token?
