    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.
