Bootstrapping functionality is now available in Oracle Cloud Infrastructure Data Flow. Your PySpark applications might need custom dependencies in the form of Python wheels or virtual environments. Your Java or Scala applications might need additional JAR files that you can't, or don't, want to bundle in a Fat JAR. Or you might want to include native code or other assets to make available within your Spark runtime. Data Flow now allows you to provide a ZIP archive in addition to your application.
