The data is transmitted in a binary form for increased efficiency. JSON topics are stateful: their state is maintained on Diffusion™ Cloud. Binary topics A topic that streams binary data as bytes and uses efficient binary deltas to stream only the data that changes between updates. Binary topics are stateful: their state is maintained on Diffusion™ Cloud. Single value topics A topic that streams data as a single value that can be constrained to a defined data type. Single value topics are stateful: their state is maintained on Diffusion™ Cloud. Record topics A topic that streams data in Diffusion™ Cloud record format. Record format comprises strings separated by field or record delimiters or both. Record topics are stateful: their state is maintained on Diffusion™ Cloud. Stateless topics A topic that has no state held on Diffusion™ Cloud or on the client that publishes to it. Routing topics A special type of topic, which can map to a different real topic for every client that subscribes to it. In this way, different clients can see different values for what is effectively the same topic from the client point of view. Slave topics A special type of topic that has no state of its own but is a reference to the state of another topic.
