A document's size in MongoDB can be a maximum of 16 MB, but does that mean we cannot store data that is more than 16 MB in size? There are cases where you prefer to store videos and audio files in a database rather than in the filesystem for a number of advantages, such as, a few of them are storing metadata along with them, accessing the file from an intermediate location, and replicating the contents for high availability if replication is enabled on the MongoDB server instances. GridFS is the way to address such use cases in MongoDB. We will also see how GridFS manages large content that exceeds 16 MB and will analyze the collections it uses for storing the content behind the scenes. For test purposes, we will not be using data exceeding 16 MB but something smaller to see GridFS in action.
