Example​

The data read from source is a table like this:

idnameagecard
1Joy Ding20123
2May Ding20123
3Kin Dom20123
4Joy Dom20123

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 {
source_table_name = "fake"
result_table_name = "fake1"
field_mapper = {
id = id
card = card
name = new_name
}
}
}

Then the data in result table fake1 will like this

idcardnew_name
1123Joy Ding
2123May Ding
3123Kin Dom
4123Joy Dom
