[jira] [Created] (NIFI-7525) Create a null() Subjectless Functions to support null type on Expression Language

Fabrizio Spataro created NIFI-7525:
--------------------------------------

             Summary: Create a null() Subjectless Functions to support null type on Expression Language
                 Key: NIFI-7525
                 URL: https://issues.apache.org/jira/browse/NIFI-7525
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core Framework
            Reporter: Fabrizio Spataro


Reading (and using) nifi expression language, could be useful have a function to set a "null value" easily!
Today, to resolve this, we can apply some tricks, for example: use an UpdateRecord processor with an unknown RecordPath value or convert record in text (json) and apply ReplaceText processor using a regex + *null* value.
 
This issue will propose you a new stateless function, called *null()* to retrieve a real "null value"
