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 field 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 |
