Effective in version 10.2.2, you can add dynamic complex ports to a dynamic mapping that runs on the Spark engine. Use dynamic complex ports to manage frequent schema changes to hierarchical data in complex files.
A dynamic complex port receives new or changed elements of a complex port based on the schema changes at run time. The input rules determine the elements of a dynamic complex port. Based on the input rules, a dynamic complex port receives one or more elements of a complex port from the upstream transformation. You can use dynamic complex ports such as dynamic array, dynamic map, and dynamic struct in some transformations on the Spark engine.
