             Summary: Adding Scripted Record processors
                 Key: NIFI-8273
                 URL: https://issues.apache.org/jira/browse/NIFI-8273
             Project: Apache NiFi
          Issue Type: New Feature
          Components: Extensions
            Reporter: Simon Bence
            Assignee: Simon Bence
             Fix For: 1.13.1


The *ScriptedTransformRecord* was recently added which we can use as a starting point for a few additional scripted processors for common tasks. These might be:
 * *ScriptedPartitionRecord*. Given a Record, would return the name of a 'partition' to send to. Two Records from an incoming FlowFile will go to the same outbound FlowFile if they belong to the same Partition.
 * *ScriptedValidateRecord*. Given a record, return true or false to indicate whether it should go to 'valid' or 'invalid'. This is less powerful and can easily be encapsulated within the previous one. However, it might make sense to provide it anyway, just because if you want to validate a record, it's more obvious that this is the right processor.
 * *ScriptedFilterRecord*. Given a Record, returns {{true}} to keep the Record, {{false}} to drop the Record. Can already be done using the ScriptedTransformRecord by returning {{null}}. But it does make sense to offer this anyway from a user experience point of view

All the above processors are very similar in functionalities and encapsulate each other. However the idea is to provide a set of processors that are obvious to use even if there is one that could answer all the needs by tweaking the configuration.
