Azure IoT Hub endpoint to ADLS Gen2 with custom file name format

When creating a custom endpoint in IoT Hub which sends data to a ADLS Gen2 storage account is it possible to use values from the incoming message, message body, or twin data when building out the file name format?

The default is “{iothub}/{partition}/{YYYY}/{MM}/{DD}/{HH}/{mm}“ and I would like to include other properties in the path like {deviceId} or {$twin.propery.foo}. I want to be able to organize the files using custom fields right from an IoT hub route to ADLS.

I know I can accomplish this with an EventHub Function trigger but I am hoping there is a way to do this just with the file name format.

endpoint creation for reference

Solution

  • AFAIK, custom file name format is not available while routing messages. Please see the Uservoice created for this feature here: extend the route to blob file name format with dynamic parameters such as deviceId or messageType
