Using dr
Command Line Usage: dr
The DataFlow API is typically used as an embedded component in a larger application. However, there is ample support for running a standalone DataFlow process. The following three methods are supported to execute a DataFlow application from the command line:
• A Java class file with a main method
• A RushScript file that defines an application
• A JSON graph file that defines an application
There are several utilities within the bin folder of the DataFlow Distribution that can be used to execute a DataFlow application or script from the command line. The dr.bat and dr files can be used on Windows and Linux-based systems respectively. Typical usage requires entering names of the files to be executed along with any necessary JVM or DataFlow options. Here is the basic usage:
dr [jvm_option]... [option]... <script_file | json_file | java_class_name>...
