Before you begin

You have created two file metadata connections under Metadata > File delimited in the Repository view for the following two files.
  • states.csv
  • customers.csv

For more information about centralizing metadata, see Talend Studio User Guide.

Procedure

  1. In the Repository tree view, click Metadata > File delimited. Drag and drop the customers metadata onto the workspace.
    The customers metadata contains information about customers, such as their ID, their name or their address, etc.
  2. In the dialog box that asks you to choose which component type you want to use, select tFileInputDelimited and click OK.
  3. Drop the states metadata onto the design workspace. Select the same component in the dialog box and click OK.
    The states metadata contains the ID of the state, and its name.
  4. Drop a tMap and two tLogRow components from the Palette onto the design workspace.
  5. Connect the customers component to the tMap, using a Row > Main connection.
  6. Connect the states component to the tMap, using a Row > Main connection. This flow will automatically be defined as Lookup.
