Naveen,
The NiFi expression language can be used to accomplish what you are
looking to do. First extract the "customer_id" from the main message. Then
used the routeonAttribute processor to only route files where the customer
contains only numbers.
${'customer_id':matches('[0-9].*')}
Without looking at your json messages, I can't be specific on the
expression language statement to use to extract the customer_id.
Does this help?
