How To: Creating a collection subset from collection in MongoDB

Many a time there are required to create a new collection from existing ones with the same or different size. In this blog, we will see how to create a new collection from the existing one and with a smaller size.

For Sample data, We may use Kaggle to get huge data set. In my collection, I have a total of 27414622 records. My objective is to create a new collection with a 40% size of the existing collection.

MongoDB Enterprise > db.subreddits.count()
27414622
MongoDB Enterprise >

40% of record size would be 10965848 so we have to find the last record so that we can create dump until that particular record. To achieve this:

MongoDB Enterprise > db.subreddits.find({}, {_id: 1}).sort({_id: -1}).skip(10965848).limit(1)
{ “_id” : ObjectId(“5c2f048eec3fae481c65e761”) }
MongoDB Enterprise >

Create a folder where mongodb will perform backup operation.

[sanjeevakumar@sanjeeva UseCase]$ mkdir subreddits-small

[sanjeevakumar@sanjeeva UseCase]$ cd subreddits-small

Moving to this folder I will use mongodump command to dump this specific collection in to local folder. The command would be:
[sanjeevakumar@sanjeeva subreddits-small]$ mongodump –db subreddits –collection subreddits –query ‘{ _id: {$gte: ObjectId(“5c2f048eec3fae481c65e761”)}}’
The Output of the command on terminal should look like:

Once dump is completed, a restore would be need to create desired collection. This new collection can be created in a new database or in the same database as per choice. The command would be:

[sanjeevakumar@sanjeeva subreddits-small]$ mongorestore -d subreddits_40 –collection subreddits_40 ./dump/subreddits/subreddits.bson
