MongoDB batchSize() Example

Date: 2018-03-02

This tutorial demonstrates MongoDB's cursor.batchSize() method, which controls the number of documents returned per network message. While the method itself doesn't alter the default 20-document display in the Mongo shell, it affects how data is fetched from the database, improving performance for large datasets by retrieving documents in batches. The example shows how to use batchSize() with find() and pretty() methods to display results. The tutorial uses a sample database and collection (exam_scores) to illustrate the functionality.
