Say for example a primitive data type (ex. string) can hold a name but a complex data type is capable of holding a group of strings. i.e. it can hold a group of names. WebComplex Data Types. A complex data type is a transformation data type that represents multiple data values in a single column position. The data values are called elements. Elements in a complex data type can be of primitive or complex data types. Use complex data types to process hierarchical data in mappings that run on the Spark engine. black and white squared carpet
