A feature deployment service of a provider network may deploy feature processing units (FPUs) to implement data processing features at both a provider network and edge devices. The use of FPUs may allow a client to use new features at the edge, without delays due to compliance/testing or software upgrades. An FPU includes a model and compute logic that are used to implement a data processing feature. A feature processing service deploys the FPU to an FPU engine at the provider network and also deploys the FPU to edge devices of the client's network that each include an edge FPU engine. The FPU engine at the provider network and the edge FPU engine at each edge device conform to a common specification/API, allowing deployment and use of the same FPU/data processing features at both the cloud and the edge.

A message broker of a publish-subscribe messaging system (e.g., using the MQTT protocol or other publish-subscribe protocol) detects a life-cycle event for topic subscription and notifies a publisher of the life-cycle event. The message broker may detect a transition in a number of subscribers to a topic from zero subscribers to one or more subscribers or from one or more subscribers to zero subscribers. In response, the message broker provides an indication to the publisher that the number of subscribers to the topic has transitioned from zero to one or more (or from one or more to zero). This causes the publisher to begin publishing messages on the publisher's topic (or to stop publishing messages on the publisher's topic).
