Duplicate Key Value to Key

Duplicate a key value to a new key.

Example

This example shows how to use the DuplicateKeyValueToKey transformation to duplicate the value of an existing key to a new key in the JSON record.

{
  "operation": "duplicate_key_value_to_key",
  "arguments": {
    "key": "original_key",
    "NewKey": "duplicated_key"
  }
}

Given the input record:

{
  "original_key": "some_value",
  "other_field": "other_value"
}

The output record will be:

{
  "original_key": "some_value",
  "other_field": "other_value",
  "duplicated_key": "some_value"
}
