Informatica Developer uses the following data types in Streaming mappings:

Complex file format data types. Streaming mappings can read, process, and write data in complex file formats such as, Avro, JSON, and XML.
Transformation data types. Set of data types that appear in the transformations. They are internal data types which the Data Integration Service uses to move data across platforms. Transformation data types appear in all transformations in a mapping.

When the Data Integration Service reads source data, it converts the native data types to the comparable transformation data types before transforming the data. When the Data Integration Service writes to a target, it converts the transformation data types to the comparable native data types.

For more information about transformation data types, see the

Big Data Management User Guide
