Quality of Service (QoS) Guidelines for External Databus Integration
To ensure optimal performance and reliability, the following QoS usage recommendations apply when configuring bridges with the External Databus: Avoid using QoS 1 and QoS 2 in bridge configurations whenever possible, as they can lead to message accumulation and memory issues in the event of connection disruptions or broker failures. If QoS 1 or QoS 2 must be used, it is critical to ensure stable connectivity and broker availability. Recovery Procedure After Broker Failure
In the event of a broker failure, residual QoS 1 and QoS 2 messages may persist in memory. To clear this and restore normal operation, follow the restart sequence below: - Restart the Databus. - Restart the External Databus.
