Big Data Management Engines

When you run a big data mapping, you can choose to run the mapping in the native environment or a Hadoop environment. If you run the mapping in a Hadoop environment, the mapping will run on one of the following job execution engines:

Blaze engine

Spark engine

Hive engine

For more information about how Big Data Management uses each engine to run mappings, workflows, and other tasks, see the chapter about Big Data Management Engines.
