AWS IoT Core Adds the Ability to Configure Quality of Service (QoS) for Republish Action

Starting today, AWS IoT Core customers can configure the quality of service (QoS) when publishing messages via the republish action of a topic rule. AWS IoT Core supports QoS levels 0 and 1 for MQTT messages, where QoS 0 means a message is delivered zero or more times and QoS 1 means message is delivered one or more times. See AWS IoT MQTT documentation for more details about AWS IoT QoS definition.
