--------------------------------------
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"
