Importing the actors data into Neo4j

Procedure

  1. Double-click the first tFileInputDelimited component to open its Basic settings view on the Component tab.
  2. In the File name/Stream field, specify the path to the CSV file that describes the actors' names, the years they were born in, and their roles in the movies.
    The input CSV file used in this example is as follows:
    Name;Born
Keanu Reeves;1964
Laurence Fishburne;1961
Carrie-Anne Moss;1967
  3. In the Header field, specify the number of rows to skip as header rows. In this example, the first row of the CSV file is the header row.
  4. Click the [...] button next to Edit schema to open the Schema dialog box, and define the input schema based on the structure of the input file. In this example, the input schema is composed of two columns, name and born, both of type String.
    When done, click OK to close the Schema dialog box and propagate the schema to the next component.
  5. Click the first tNeo4jOutput component and select the Component tab to open its Basic settings view.
  6. Select the Use an existing connection check box to reuse the Neo4j database connection opened by the tNeo4jConnection component, which is the only connection component used in this example.
  7. Double-click the tNeo4jOutput component or click the Mapping button on the component's Basic settings view to open the index and relationship mapping editor.
  8. With the name column selected from the schema panel, click the Index creation tab, click the [+] button to add a row in the table, and create an index named name on this column:

    • In the Name field, enter name between double quotation marks.

    • In the Key field, enter name between double quotation marks to give the index a key name.

    Then click in the schema panel to validate your index creation, and click OK to close the mapping editor.
  9. Select the Use label (Neo4j > 2.0) check box and enter Actors between double quotation marks in the Label name field so that the nodes to be created will be labeled Actors.
