In the previous recipe, we saw how to store data to GridFS using the command-line utility called mongofiles
, which comes with MongoDB to manage large data files. To get an idea of what GridFS is and what collections are used behind the scenes to store the data, refer to the previous recipe. In this recipe, we will look at storing data to GridFS using a Java client. The program will be a highly scaled down version of the mongofiles
utility and focuses only on how to store, retrieve, and delete data rather than trying to provide a lot of options such as mongofiles
do.
Refer to the Connecting to a single node from a Java client recipe from Chapter 1, Installing and Starting the MongoDB Server, for all the necessary setup for this recipe.
