You can generate a Job to match data in a specific file in the Studio metadata against data in another data source. Using the settings of the components of this automatically-generated Job, you can choose to output the exact match and nonmatch values in separate files or in a database. However, you can choose to output possible matches in a file, a database or in the stewardship console. To do this, you must configure the Talend Data Stewardship Console web application.
The Talend Data Stewardship Console is deprecated since Talend 6.4. Consider migrating to .
For more information about data resolution, see the Talend Data Stewardship Console User Guide.
The sequence of matching data against a lookup file involves the following steps:
Selecting the file that holds the data you want to match.

If required, defining a blocking key to partition the data to be processed. A blocking key is usually needed when there is a lot of data in the file.
