How to implement atamarity in MongoDb?

Question

MongoDB

Good afternoon.
I have a mongodb database where multiple nodes handle reading and writing documents. You need to make sure that only one process can work with the document at a time. That is, I need to lock the database at some point, and then release it after the process has completed and updated the records, that is, so that only one process can update my records, and several at the same time.
