问题 I have a 2 GB CSV file with 9 M records that I import into MongoDB using the native mongoimport tool. It imports the CSV at a rate of 8K per second. The overall time taken is 10 minutes. The speed of import is quite reasonable, but it seems to be much slower than the MySQL LOAD DATA INFILE version(takes only 2 minutes to insert all of the records into the database).

The collection is like this: { id:"122234343", name: "name1", children: ["222334444","333344444"] } One approach I tried is to create 2 csv files - one with id & name and other with id, children (if id has two children then it will have two rows). Import the data into two different collections using mongoimport and then use update the collection data using foreach() at second collection having children data. Please
