Similar records are grouped together. The number of records in each group is
listed in the GRP_SIZE column and computed only on the
master record. The MASTER column indicates with true or false if
the corresponding record is a master record or not a master record. The master
record is created by merging the record which best matches the phonetic
algorithms with the record which has the largest age value. The
SCORE column lists the calculated similarity between
the input record and the master record according to the Soundex matching algorithm.
The identifier for each group, which is of String data
type, is listed in the GID column next to the corresponding
record. This identifier will be of the data type Long for
Jobs that are migrated from older releases. To have the group identifier as
String, you must replace the tMatchGroup component in the imported Job with tMatchGroup from the studio Palette.
