I am trying to implement a ranking system.
Like Facebook or Instagram, if you click "Like", the ranking will be tallied by that number.
But the question is, if two or more people press "Like" on one post at a time, is there any problem with counting?
According to the post’s tag, It looks like you want to implement your functionality with Player Data or statistics. PlayFab's Player Data does not have a rank function, and we only have rank on statistic, but it cannot carry the contents. You may try to use Economy V2 UGC to implement it. PlayFab User Generated Content (UGC) empowers your players to create, upload, and search for content. And it has a review system, players can attach a rating or review to an item by calling the ReviewItem API, but PlayFab doesn't have a native feature like you claim (people press "Like" on one item). When a player finish rating an item, the total count of this item's rating will be incremented by one. You can think of this "total count" as a "Like", then players can use API SearchItems to execute a search against the public catalog using the provided search parameters(you can set the search parameters to the descending order with total count, in this way, the rank function of "Like" can be realized).
