Loading the Yelp dataset into MongoDB

In a previous post, I downloaded the Yelp dataset, 5.79GB of json data. My first thought (before I get to experimenting with Apache Spark), was how can I extract some basic stats from this dataset, basics like how many data items are there, and what do the records look like in each of the data files.

Using mongoimport and referring to the docs here, the syntax for the import is:

mongoimport -d database -c collection importfile.json

Here’s the Yelp dataset json file for importing, to get an idea of the size of each file:

kev@esxi-ubuntu-mongodb1:~/data/yelp$ ls -lS

total 5657960

-rwxrwxr-x 1 kev kev 3819730722 Oct 14 16:16 review.json

-rwxrwxr-x 1 kev kev 1572537048 Oct 14 16:22 user.json

-rwxrwxr-x 1 kev kev  184892583 Oct 14 16:16 tip.json

-rwxrwxr-x 1 kev kev  132272455 Oct 14 16:03 business.json

-rwxrwxr-x 1 kev kev   60098185 Oct 14 16:03 checkin.json

-rwxrwxr-x 1 kev kev   24195971 Oct 14 16:03 photos.json

 

So importing each of the datasets, one at a time:

kev@esxi-ubuntu-mongodb1:~/data/yelp$ mongoimport -d yelp -c checkin checkin.json
