Use Data Processing Engine (DPE) to read data from context definitions and write it to JSON to support high-volume data transformations for processes such as document generation. Use DPE in place of Apex plug-ins to scale transformations for complex product hierarchies and groupings without hitting governor limits.
Where: This change applies to Lightning Experience in Professional, Enterprise, Unlimited, and Developer editions where Data Processing Engine and Data Processing Engine On Demand are available.
Who: To use this feature, you need the Data Processing Engine On Demand permission set license and the Run Data Processing Engine Definitions On Demand permission set.
How: In a DPE definition, select a context definition as the data source. To send transformed data to downstream processes, create a JSON type Writeback Object node.
