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.
