将数据转换为 JSON

Question

I am consuming in Nifi messages from a Kafka topic.

enter image description here

Although I want to convert this messages into a Json with the following attributes:

datetime, machineID, volt, rotate, pressure, vibration.

How can I do that, I tried several processors and none of those worked.

Answer 1

if you use the ConsumerKafkaRecord processor you can use the Record Reader and the Record Writer so that NiFi can generate a json as you wish. Nifi Doc Otherwise if you have a csv and want to transform a csv to json you can use ConvertRecord Stack Doc
