             Summary: PutLambda Nifi expression in Function Name and Region values
                 Key: NIFI-11534
                 URL: https://issues.apache.org/jira/browse/NIFI-11534
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core Framework
            Reporter: Ernestas Žemaitis
         Attachments: AbstractAWSLambdaProcessor.java, PutLambda.java, Screenshot 2023-05-09 at 14.29.48.png, Screenshot 2023-05-09 at 14.30.16.png

As of NiFi 1.21.0 PutLambda doesn't allow to +pass flow file attributes+ to _+Function Name+_ and +_Region_+ fields (see pictures in attachments). The lack of this feature complicates our workflows because it requires to have each processor assigned to specific lambda and if the flow has a lot of lambdas, that becomes a mess really quickly.

By allowing to use nifi expression language in _+Function Name+_ & +_Region_+ fields, it simplifies certain nifi flows and makes better nifi usage experience.

In attachment, I add some code examples of how this change could be implemented. Be aware that these examples contains some additional changes for NIFI-11533 as well.
