This scenario applies only to Talend Data Management Platform, Talend Big Data Platform, Talend Real Time Big Data Platform, Talend Data Services Platform, Talend MDM Platform and Talend Data Fabric.

This scenario describes a basic Job that compares columns in the input file using the Jaro-Winkler matching method on the lname and fname columns. It then groups the output records in output flows:
  • Uniques: lists the records which group size (minimal distance computed in the record) is equal to 1.

  • Matches: lists the records which group quality is greater than or equal to the threshold you define in the Confident match threshold field.

  • Suspects: lists the records which group quality is less than the threshold you define in the Confident match threshold field.

The group quality is the minimal distance computed among all record pairs of the group.
