A schema created as Built-in is meant for a single use in a Job, hence cannot be reused in another Job.


  1. Select Built-in in the Property Type list of the Basic settings view.
  2. Click the Edit Schema button to create your built-in schema by adding columns and describing their content, according to the input file definition.
    Warning: Avoid using any Java reserved keyword as a schema column name.
    Make sure the data type in the Type column is correctly defined.
    For more information regarding Java data types, including date pattern, see Java API Specification.
    Below are the commonly used Talend data types:
    • Object: a generic Talend data type that allows processing data without regard to its content, for example, a data file not otherwise supported can be processed with a tFileInputRaw component by specifying that it has a data type of Object.

    • List: a space-separated list of primitive type elements in an XML Schema definition, defined using the xsd:list element.

    • Document: a data type that allows processing an entire XML document without regarding to its content.

    In all output properties, you also have to define the schema of the output. To retrieve the schema defined in the input schema, click the Sync columns tab in the Basic settings view.


    When creating a database table, you are recommended to specify the Length field for all columns of type String, Integer or Long and specify the Precision field for all columns of type Double, Float or BigDecimal in the schema of the component used. Otherwise, unexpected errors may occur.
