Low Fanout topic spaces cannot overlap each other.The only topic space types that are supported in this release are LowFanout and PublishOnly.Pub/sub on system topics do not require topic spaces. To publish or subscribe to any topic, a matching topic space must be configured.To enable pub/sub on sample/#, configure TopicSpace using the below Azure CLI command:.Let us get started with a hello world scenario, with a publisher and subscriber communicating on a topic.īelow table enumerate the devices, topics and topic space used in this example. The samples use authentication based on SharedAccessKeys.
