Importing a Complex Data Type Definition

Importing a Complex Data Type Definition

A complex data type definition represents the schema of the data of type struct. You can import the schema of the hierarchical data in the complex file to the type definition library as a complex data type definition.
Import complex data type definitions from an Avro, JSON, or Parquet schema file. For example, you can import an Avro schema from an .avsc file as a complex data type definition.
  1. In the Developer tool, open the mapping or mapplet where you want to import a complex data type definition.
  2. In the
    Outline
    view, select the
    Type Definition Library
    to view the
    Type_Definition_Library
    tab in the mapping editor.
  3. Right-click an empty area of the editor and click
    Import Complex Data Type Definitions
    .
    The
    Import Complex Data Type Definitions
    dialog box appears.
  4. Select a complex file format from the
    File Format
    list.
  5. Click
    Browse
    to select the complex file schema from which you want to import the complex data type definition.
  6. Navigate to the complex file schema and click
    Open
    .
  7. Click
    Next
    .
    The
    Choose Complex Data Type Definitions to Import
    page appears.
  8. Select one or more schemas from the list to import.
  9. Click
    Next
    .
    The
    Complex Data Type Definitions to Import
    page appears.
  10. Review the complex data type definitions that you want to import and click
    Finish
    .
    The complex data type definition appears in the
    Type Definition Library
    tab of the mapping or the mapplet.
