Complex Ports in Transformations

You can create complex ports in some transformations that are supported on the Spark and Databricks Spark engines. Read and Write transformations can represent ports that pass hierarchical data as complex data types.

You can create complex ports in the following transformations:

Aggregator

Expression

Filter

Java

Joiner

Lookup

Normalizer

Router

Sorter

Union

The Databricks Spark engine does not support the Java transformation.

The Read and Write transformations can read and write hierarchical data in complex files. To read and write hierarchical data, the Read and Write transformations must meet the following requirements:

The transformation must be based on a complex file data object.

The data object read and write operations must project columns as complex data types.
