The data read from source is a table like this:

name age card
Joy Ding 20 123
May Ding 20 123
Kin Dom 20 123
Joy Dom 20 123

We want copy fields name、age to a new fields name1、name2、age1, we can add Copy Transform like this

  1. transform {
  2.   Copy {
  3.     source_table_name = "fake"
  4.     result_table_name = "fake1"
  5.     fields {
  6.       name1 = name
  7.       name2 = name
  8.       age1 = age
  9.     }
  10.   }
  11. }

Then the data in result table fake1 will like this

name age card name1 name2 age1
Joy Ding 20 123 Joy Ding Joy Ding 20
May Ding 20 123 May Ding May Ding 20
Kin Dom 20 123 Kin Dom Kin Dom 20
Joy Dom 20 123 Joy Dom Joy Dom 20
