Rename Columns

It lets the user rename one or multiple column(s) at once.

This transformation expects user to provide below inputs:

Input Arguments	Mandatory	Default Value	Description
rename-column-mapper	Yes	-	It defines the mapping of the existing and desired column name

Now, suppose the requirement is to rename above columns like below:

col_A -> test_col_A
col_B -> COL_b
col_C -> my_column

Then, user can configure the RenameColumns transformation in the below manner:

{
  type = "RenameColumns"
  rename-column-mapper = {
    "col_A" = "test_col_A"
    "col_B" = "COL_b"
    "col_C" = "my_column"
  }
}

The transformed response will now have the columns with the desired name:

{
  "test_col_A": 5,
  "COL_b": 4,
  "my_column": 3.4678
}
