PowerExchange Condense is an optional component that reads change data from PowerExchange Logger log files and writes the data to condense files. If multiple changes have been made to the same record, PowerExchange Condense reduces the volume of the change data by storing only the oldest before image and the latest after image of that record. PowerExchange Condense also re-sequences the change records into the transaction commit order and eliminates any change records that were rolled back.
