@Thinhhoagn0211 , Nope, the built in MQTT export function from the SDK doesn't support publishing to multiple topics. I looks like the config you posted is modified from the cloud-export-mqtt example, correct? The If you are already creating a custom app service to do your data transform prior to export, you could also create your own custom MQTT Export function (based from the source from the SDK version) and expand it to support multiple topics. You could also submit a feature request Issue on the app sdk to support export to multiple topics. We would then consider it for the Odessa 3.2 release in Spring 2024. |
