field.exclude

Remove a subset of fields from the record.

Description​

Remove a subset of fields from the record, all the other fields are left untouched. If a field is excluded that contains nested data, the whole tree will be removed. It is not allowed to exclude .Position or .Operation fields.

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.

Exclude multiple fields​


It's possible to exclude multiple fields by providing a
comma-separated list of fields. In this example, we exclude .Metadata,
.Payload.After.foo and .Key.key1.
