Abstract:
Complete and partial object publication using, for example, MQTT or other protocol is described. In some embodiments, an emphasis is placed on keeping the amount of state information that the broker must maintain to a minimum, as well as allowing idempotent operations over objects in order to keep the object view between the subscribers consistent. Embodiments are described in which only the parts of an object have changed are transferred to the subscribers who subscribe to that object.
