|
A cursor typically fetches a batch of result objects and store them
|
|
locally. This method sets the batchSize value to configure the amount of
|
|
documents retrieved from the server in one data packet.

The number of results to return per batch. Each batch requires a

round-trip to the server.

This cannot override MongoDB's limit on the amount of data it will return to
|
|
the client (i.e., if you set batch size to 1,000,000,000, MongoDB will still
|
|
only return 4-16MB of results per batch).
