the type into which Change Events are deserialized

The operation time before which all Change Events are known. Must be in the time range of the oplog. (since MongoDB 4.0)

A sequence of aggregation stages to apply on events in the stream (see MongoDB documentation for a list of valid stages for a change stream).

The maximum amount of time in milliseconds the server waits for new data changes before returning an empty batch. In practice, this parameter controls the duration of the long-polling behavior of the cursor.
