Today we are using the .estimated_document_count() method from the pymongo library. According to the documentation, this method is faster than .count_documents() but its result is an estimate of the number of documents in this collection. Therefore, it introduces uncertainty into the result. On the other hand, .count_documents() is slower but accurate. In addition to accepting a filter as a parameter.
