Description
Modifies the contents of a FlowFile that contains Record-oriented data (i.e. data that can be read via a RecordReader and written by a RecordWriter) by removing selected fields. This Processor requires that at least one user-defined Property be added. The name of the property is ignored by the processor, but could be a meaningful identifier for the user. The value of the property should indicate a RecordPath that determines the field to be removed. The processor executes the removal in the order in which these properties are added to the processor. Set the "Record Writer" to "Inherit Record Schema" in order to use the updated Record Schema modified when removing Fields.

    Configuration
    Configure the Record Reader according to the incoming data format.
Configure the Record Writer according to the desired output format.

For each field that you want to remove, add a single new property to the Processor.
The name of the property can be anything but it's recommended to use a brief description of the field.
The value of the property is a RecordPath that matches the field to remove.

For example, to remove the `name` and `email` fields, add two Properties:
`name` = `/name`
`email` = `/email`
