cursor.batchSize(size)

Important

mongosh Method

This page documents a mongosh method. This is not the documentation for a language-specific driver, such as Node.js.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

Specifies the number of documents to return in each batch of the response from the MongoDB instance. In most cases, modifying the batch size will not affect the user or the application, as mongosh and most drivers return results as if MongoDB returned a single batch.

The batchSize() method takes the following parameter:

Parameter
Type
Description
size
integer
The number of documents to return per batch.

The following example sets the batch size for the results of a query (i.e. find()) to 10. The batchSize() method does not change the output in mongosh, which, by default, iterates over the first 20 documents.

db.inventory.find().batchSize(10)
