Procedure

  1. Rename the schema (by default, metadata) and edit the schema columns as needed.
    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.

    • Dynamic: a data type that can be set for a single column at the end of a schema to allow processing fields as VARCHAR(100) columns named either as ‘Column<X>’ or, if the input includes a header, from the column names appearing in the header. For more information, see Dynamic schema.

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

  2. To retrieve or update the Regex File schema, click Guess. Note however that any edits to the schema might be lost after guessing the file based schema.
  3. When done, click Finish to close the wizard.
