" + Review comment: You are right, I checked back the existing partition processor. However I see the merit of both behaviour so I decided to separate the two different business logic into two different processors. One is for partitioning, which mimics the behaviour of the existing `PartitionRecord` from most of the aspects (but of course depending on the script evaluation) and I also added a `ScriptedRoutingRecord` which based on the script result and the pre-configured variables will transfer the flow files into different routes without additional steps. -- This is an automated message from the Apache Git Service.
