Parse server: How to get exact amount of registered users
I have several millions of users in by database. Is there a way how i can get the exact amount of users registered?
I want to implement a live user registration counter.
The default way is to use the count query from the sdk, but it has limitation to 1000 rows. I need a solution for millions of rows, without any additional indexing or modifications to the DB. Is there such?

The 1000 query limit is for the old parse.com server.
On parse-server, this limit has been removed and you can count above 1000.
https://docs.parseplatform.org/js/guide/#counting-objects
You should note that this is an expensive query and you should consider creating an object that stores the total number of users and increases when a new user is created.
You can do this with afterSave triggers
e.g
Parse.Cloud.beforeSave(Parse.User, async(req) => {
if (!req.object.existed()){
const userCount = await new Parse.Query('Statistics').equalTo('name', 'user_count').first({useMasterKey: true});
userCount.increment('count');
userCount.save(null, {useMasterKey: true});
}});
