  • Creating external data flows

    External Data Flow (EDF) is a rule for defining the flow of data on the graphical canvas and executing that flow on an external system. With EDF, you can run predictive analytics models in a Hadoop environment and utilize its infrastructure to process large numbers of records to limit the data transfer between Hadoop and the Pega Platform.
