Mongo aggregaton does not return whole result only a part of it

Question

Can somebody tell me please where is the problem in this simple aggregation command:

db.test.aggregate([
    {
         $group: {
             _id: "$type",
             numbers: { $sum: 1 }
         } 
    }
]).pretty()

Collection has about 2 millions of documents and everyone has type field. But the result returns only few of them as result + message "Type "it" for more" If I type "it" it returns next partial aggregation result till the end. But I want to have the whole aggregation in one result. What am I doing wrong? Thanks.

Answer 1

MongoDB won't return you whole bunch of data because it has built-in pagination.

In other case (2 mil of documents) would crash your server/computer as it runs out of memory.

But, if you'd like to get all bunch of data, it's better to store it with script.
You can write script with your programming language, request db, paginate through data and store in some variable.
