Final: Question 6
Suppose you have a collection of students of the following form:
{
"_id" : ObjectId("50c598f582094fb5f92efb96"),
"first_name" : "John",
"last_name" : "Doe",
"date_of_admission" : ISODate("2010-02-21T05:00:00Z"),
"residence_hall" : "Fairweather",
"has_car" : true,
"student_id" : "2348023902",
"current_classes" : [
"His343",
"Math234",
"Phy123",
"Art232"
]
}
Now suppose that basic inserts into the collection, which only include the last name, first name, and student_id, are too slow (we can’t do enough of them per second from our program). What could potentially improve the speed of inserts? Check all that apply.
Solution: I selected as in the image, please let me know if there are any correct answer.
