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.</p><p><a href="additionalDetails.html">Additional Details...</a></p><h3>Tags: </h3><p>update, record, generic, schema, json, csv, avro, log, logs, freeform, text</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
