getMore¶

3.2 新版功能.

Use in conjunction with commands that return a cursor, e.g. find and aggregate, to return subsequent batches of documents currently pointed to by the cursor.

The getMore command has the following form:

{
   "getMore": <long>,
   "collection": <string>,
   "batchSize": <int>,
   "maxTimeMS": <int>
}

The command accepts the following fields:

Field	Type	Description
`getMore`	long	The cursor id.
`collection`	string	The name of the collection over which the cursor is operating.
`batchSize`	positive integer	Optional. The number of documents to return in the batch.
`maxTimeMS`	positive integer	Optional. The maximum time period in milliseconds the `getMore()` operation will block waiting for new data to be inserted into the capped collection. Requires that the cursor on which this `getMore()` is acting is an `awaitData` cursor. See the `awaitData` parameter for `find()`.
