Recommend adjusting the wording to include more details about the expected format, along the following lines: The Apache IoTDB Schema Template defined using JSON. The Processor will infer the IoTDB Schema when this property is not configured. The [IoTDB Schema Template](https://iotdb.apache.org/UserGuide/Master/Data-Concept/Schema-Template.html) documentation provides some details, but is there an official format specification? It would be helpful to link to that documentation if available, otherwise it will be unclear how to define this property. -- This is an automated message from the Apache Git Service.
