Example

The data read from source is a table like this:

id	name	age	card
1	Joy Ding	20	123
2	May Ding	20	123
3	Kin Dom	20	123
4	Joy Dom	20	123

We want to delete age field and update the filed order to id, card, name and rename name to new_name. We can add FieldMapper transform like this

transform {
  FieldMapper {
    plugin_input = "fake"
    plugin_output = "fake1"
    field_mapper = {
        id = id
        card = card
        name = new_name
    }
  }
}

Then the data in result table fake1 will like this

id	card	new_name
1	123	Joy Ding
2	123	May Ding
3	123	Kin Dom
4	123	Joy Dom
