How to find out about data changes in the Mongodb database?

Question

Python

Hello everyone, there is a Mongodb database, as soon as some kind of database change occurs (delete, write, change ..) get the changed data. That is, viewing changes in real time or almost.
I am working on Python 3.7. How to do this, tell me, the second day I'm sitting on this.

Answer 1

There are also Change Streams
Examples for python are in the documentation

Answer 2

As an option to read the oplog
The oplog (operations log) is a special capped collection that keeps a rolling record of all operations that modify the data stored in your databases.
Google in this direction, I suppose there are already ready-made parsers for this oplog.
