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
