Azure IoT Device SDK - AVRO RRS feed

  • Question

  • Dear all,

    I am using the azure iot sdk to send message successfully to the IOT Hub, and notice that it is using AVRO format.  Is it possible to change it to use JSON?  I got lost in the github source code looking for this.

    Thank you.

  • Hello chuaky,

    In fact IoT Hub doesn’t crack the message payload,it just treats the message as bytes across the wire.Compression is a very common need in IoT scenarios because most large scale IoT solutions include message aggregation and compression before sending the messages across the wire.XML and JSON are expressive, but they’re big, and slow to process. If you need not to use compression and then process those messages post-ingestion,you can send any format message data to IoT Hub. But if you use  compression and then process those messages post-ingestion, such as Azure Stream Analytics, a common Azure IoT message ingestor, it supports JSON, CSV and Avro.

    Best Regards,

    Michael
