Remarks

Breaking up large quantities of data can be useful for keeping the flow of MQTT messages flowing through the system. Because MQTT ensures in-order delivery of QoS 0 messages on the same topic, very large messages can result in messages being blocked while delivery of large messages takes place.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
