You can perform run-time processing in the native environment or in a non-native environment. The native environment is the Informatica domain where the Data Integration Service performs all run-time processing. Use the native run-time environment to process data that is less than 10 terabytes. A non-native environment is a distributed cluster outside of the Informatica domain, such as Hadoop or Databricks, where the Data Integration Service can push run-time processing. Use a non-native run-time environment to optimize mapping performance and process data that is greater than 10 terabytes.
