Effective in version 10.2.1, you can use a complex operator in mappings that run on the Spark engine to access elements in a map data type.
Map data type contains an unordered collection of key-value pair elements. Use the subscript operator [ ] to access the value corresponding to a given key in the map data type.
For more information about complex operators, see the "Operators" chapter in the
Informatica 10.2.1 Developer Transformation Language Reference.
