question

Can playfab provide Daily, Weekly, Monthly, Global and Lifetime leaderboard?

When you create a PlayFab leaderboard, you can set the reset frequency for it as Manually, Hourly, Daily, Weekly or Monthly. And our leaderboard feature can support the global leaderboard well. Regarding Lifetime leaderboard, you can choose not to reset your total statistics. For more detai, you can refer to Using resettable statistics and leaderboards.

Are all leaderboards realtime or there will some latency based on leaderboard? Daily leaderboard provides ranks in realtime, but is it same for all other leaderboards or there is latency like leaderboard refresh after every 3 hours or so?

Our leaderboards are updated when players update their statistics. Since it is technically impossible for the leaderboard to be updated within the same millisecond that a new score is reported, this may have a delay of one to two seconds. All leaderboards are the same.

I will have approx 50 tournament at same time with 10 levels in each tournament, and I need 3 types of leaderboard with 10 rules(Max 6's, Max4's, etc..) on each 3 types on all 10 levels for 50 tournaments. Can playfab support it. it will be around 15000 leaderboards

You can navigate to your title's [Game Manager] -> [Title settings] -> [Limits] to check all limits of your title. The limit of leaderboard is the same as the limit of player statistics, it’s 300. You can upgrade the limit with an Enterprise Plan. Considering you need so many leaderboards, you may Contact us (playfab.com) to discuss the details.

I will be having 10M DAU users with 100000 QPS where every user will update his score in approx 300 sec. Can playfab handle this traffic
