    Billing multipliers

    The QoS and cleanSession parameters affect billing when you transmit messages over the MQTT protocol. Each message, whether from a client API or cloud API call, counts as one basic billing unit. This unit is multiplied by a billing multiplier based on the transmission quality level.

    The following table lists the billing multipliers for ApsaraMQ for MQTT messages.

    Transmission quality level

    Billing multiplier

    MQTT protocol with QoS=0 and cleanSession=true
