AWS IoT Core Provides potential to Configure Quality of Service (QoS) for Republish Action

AWS IoT offers reliable, two directional communication between Internet associated devices sensors, actuators, embedded micro-controllers, or smart appliances and the AWS Cloud. AWS IoT allows you to gather telemetry data from different devices, and save and analyze the data. Further you can design applications which allow your users to handle these devices from their phones or tablets. Now AWS IoT Core customers can configure the quality of service (QoS) when broadcasting messages through the republish action of a topic rule. AWS IoT Core helps 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. Refer AWS IoT MQTT documentation for further information on AWS IoT QoS definition. Earlier, the republish action would broadcast messages as QoS 0. With this new feature to configure the QoS of messages publicize through the republish action, now customers have choice to broadcast their major messages as QoS 1 and have subscribers acknowledge the reception of these messages if they also subscribe as QoS 1. Additionally, in mixture with persistent sessions. To get the further information about this feature, read the republish action documentation.
