Hi @gogangipark,

Currently the PutInfluxDatabaseRecord only evaluates tags and fields over Apache NiFi Record.

You could update your record by the UpdateRecord processor.

To add a tag field to your record use following configuration:

Is it OK for you?

Hi,
Pardon me to write things in a closed issue. I need to write the data as line protocol to Kafka brokers. Therefore I make heavy use of InfluxLineProtocolRecordSetWriter. I need to dynamically change the tags and fields in the writer, but I cannot do that for tags and fields.

I noticed that I can easily change the measurement with a field in the data. Is it possible to make both tags and fields to read from either attributes or fields in the data like the measurement field?

Thanks for your replies.
