    • Considers any consecutive records with the same key value to be in the same group. If a group consists of one record, writes that record to the out port. If a group consists of more than one record, uses the value of the keep parameter to determine which record — if any — to write to the out port, and which record or records to write to the dup port. If you have chosen unique-only for the keep parameter, does not write records to the out port from any groups consisting of more than one record.
