Abstract
Methods, systems, apparatuses, and computer-readable storage mediums are described for bridging brokers of messages from Internet of Things (IoT) devices. In an example system, a first message broker receives a message and an associated topic from an IoT device. A bridging coordinator accesses a topic-to-broker map that indicates, for a second broker, a list of topic filters for which the second message broker has at least one subscriber. The bridging coordinator determines whether the list of topics includes the associated topic. In response to a determination that the list of topic filters in the topic-to-broker map includes the associated topic, the bridging coordinator forward the message to the second message broker. In response to a determination that the list of topic filters does not include the associated topic, the bridging coordinator prevents forwarding of the message to the second message broker.
