Comparing columns and grouping in the output flow duplicate records that have the same functional key

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

For more technologies supported by Talend, see Talend components.

This second scenario describes a Job that aims at:

  • generating a functional key using one algorithm on one of the input columns, DoB as described in scenario 1.

  • matching two input columns using the Jaro-Winkler algorithm.

  • grouping the output columns by the generated functional key to optimize the matching operation and compare only the records that have the same blocking value, functional key in this scenario. For more information on grouping output columns and using blocking values, see tMatchGroup.
