Create Key

Creates a new key-value pair if the target key-value exists in the record.

Example

This example shows how to use the CreateKeyValueIfKeyValue transformation to add a new key-value pair to a record if another key-value pair exists.

Code
{
    "operation": "create_key_value_if_key_value",
    "arguments": {
		"key": "new_field",
		"value": "new_value",
		"key_to_watch": "existing_field",
		"value_to_watch": "existing_value"
	}
}

Given the input record:

Code
{
    "existing_field": "existing_value"
}

The output record will be:

Code
{
    "existing_field": "existing_value",
    "new_field": "new_value"
}

If the input record does not contain the key_to_watch with the specified value_to_watch, no changes will be made to the record.
