@flovilmart I dismissed your review, can you approve and merge?

dplewis, can I perform a distinct query from an iOS app? I did not see it in the doc and in the issues about distinct it looks like it may need to be done from a cloud function. Can you give me a bit more info please?

Distinct requires Master Key so it can’t be used on the client side. Cloud code should be used in your case.

[LilMoke]

So do you have an example of how it would be used? Cloud code is fine, my backend is Node.js. Thanks for the info.

You can check the JavaScript guide.

const query = new Parse.Query("User");
query.distinct("age")
.then(function(results) {
// results contains unique age
})
.catch(function(error) {
// There was an error.
});
