maxAwaitTime(duration: Duration): FindObservable[TResult]
The maximum amount of time for the server to wait on new documents to satisfy a tailable cursor query.
The maximum amount of time for the server to wait on new documents to satisfy a tailable cursor query. This only applies to a TAILABLE_AWAIT cursor. When the cursor is not a TAILABLE_AWAIT cursor, this option is ignored.
On servers >= 3.2, this option will be specified on the getMore command as "maxTimeMS". The default is no value: no "maxTimeMS" is sent to the server with the getMore command.
On servers < 3.2, this option is ignored, and indicates that the driver should respect the server's default value
