UpdateRecord 2.3.0¶

BUNDLE¶

org.apache.nifi | nifi-standard-nar

DESCRIPTION¶

Updates the contents of a FlowFile that contains Record-oriented data (i.e., data that can be read via a RecordReader and written by a RecordWriter). This Processor requires that at least one user-defined Property be added. The name of the Property should indicate a RecordPath that determines the field that should be updated. The value of the Property is either a replacement value (optionally making use of the Expression Language) or is itself a RecordPath that extracts a value from the Record. Whether the Property value is determined to be a RecordPath or a literal value depends on the configuration of the <Replacement Value Strategy> Property.
