Pymongo : keep creating new ids

In a pymongo project I'm working on, in a particular collection, I have to keep uploading name and age of people who will be entering them. I have to identify them with unique ids.

What I as planning to do is start the first id from 1. When inserting data, I first read the whole collection, find the number of records and then save my record with the next id. (eg. I read, and I find that there are 10 records, then the id of my new record will be 11).

But is there any better way to do it?

MongoDB already assigns unique id to each document which can be sorted in ascending order. If you don't wanna use that then you can create a separate collection which should just contain 1 document with totalRecordsCount. And increment it every time you add new record and get latest number before adding new record. This is not a best way but you will be able to avoid reading whole collection.
