From the Profiling perspective, you can create match rules with the VSR or the T-Swoosh algorithm and save them in the Studio repository. Once centralized in the repository, you can import them in the match analysis editor and test them on your data to group duplicate records. For further information about the match analysis, see Creating a match analysis above.
You can also import rules defined with the VSR algorithm in the tMatchGroup configuration wizard and in other match components, including the Hadoop components, and use the rules in match Jobs. For further information, see the tMatchGroup documentation.
The master record is simply selected to be the first input record with the VSR algorithm. Therefore, the list of match groups may depend on the order of the input records,
The output records do not change with the VSR algorithm, whereas the T-Swoosh algorithm creates new records.
