Preface

The Informatica Developer Transformation Guide contains information about transformation functionality in the Developer tool. It is written for data quality, big data, and data services developers. This guide assumes that you have an understanding of data quality concepts, flat file and relational database concepts, and the database engines in your environment.

Each of the run-time engines in the Hadoop environment can process mapping logic differently. In the Hadoop environment, Informatica transformations might be fully supported, supported with restrictions, or not supported. Similarly, in the native environment, some Informatica transformations and transformation behavior might not be supported.

Before you validate and run a mapping in the Hadoop environment, refer to the Big Data Management User Guide to learn about the transformations that are supported in the Hadoop environment and the processing restrictions.
