Add Suffix To Column Names

It lets the user add a desired suffix to select/all column names.

This transformation expects user to provide below inputs:

Input Arguments	Mandatory	Default Value	Description
suffix	Yes	-	It defines the desired suffix that will be added to the column name
column-names	no	all	It defines the list of column names to which the suffix will get added

For example, consider we have below restonomer response in json:

{
  "col_A": 5,
  "col_B": 4,
  "col_C": 3
}

Now, suppose the requirement is to add suffix to the few of the columns like below:

col_A -> col_A_old
col_B -> col_B_old

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

{
  type = "AddSuffixToColumnNames"
  suffix = "old"
  column-names = ["col_A", "col_B"]
}

The transformed response will now have the columns with the desired suffix like below. Note that, underscore character ('_') will get added automatically, separating suffix and the column name.

{
  "col_A_old": 5,
  "col_B_old": 4,
  "col_C": 3
}
