For the purpose of running your extractor using BD Development Base, you DO NOT have to change anything.

If you are planning to run your extractor using Docker, you will need to modify the Dockerfile to set these parameters required.
If you are planning to run your extractor as a standalone program (outside of Docker), you would need to set the command-line arguements and you can find the available options by running your extractor with help option(-h, --help) .
