The state store is a distributed storage system, deployed as part of Azure IoT Operations. Using the state store, applications can get, set, and delete key-value pairs, without needing to install more services, such as Redis. The state store also provides versioning of the data, and also the primitives for building distributed locks, ideal for highly available applications.

The state store is implemented via MQTTv5. Its service is integrated directly into MQTT broker and is automatically started when the broker starts. The state store provides the same high availability as the MQTT broker.
