---------------------------------
Summary: Add a RenameRecordField processor
Key: NIFI-12124
URL: https://issues.apache.org/jira/browse/NIFI-12124
Project: Apache NiFi
Issue Type: Task
Components: Extensions
Reporter: Mark Payne
The RemoveRecordField processor that was recently added has made it much
simpler to remove specific fields from a Record. However, it's still not
trivial to rename a field. There are multiple ways to achieve this, but none of
them are straight-forward.
It should take as its configuration user-defined properties such that the key
is a RecordPath and the value is a String literal or a Expression Language
Expression - much like UpdateRecord does when configured with "Replacement
Value Strategy" = "Literal Value." When evaluating EL, it should expose
FlowFile attributes as well as {{field.name}} and {{{}field.value{}}}.
