field.rename

Rename a group of fields.

Description​

Rename a group of field names to new names. It is not allowed to rename top-level fields (.Operation, .Position, .Key, .Metadata, .Payload.Before, .Payload.After).

Note that this processor only runs on structured data, if the record contains raw JSON data, then use the processor json.decode to parse it into structured data first.
