This code will produce and read a high water mark file from the same directory as the execution called ssis_hwm.txt and produce files according to the configuration JSON.
Advance options:
If you wish to maintain your own high water mark files elsewhere you can use the above section’s script as a guide on how to call the extractor. The configuration file is simply the keyword arguments in JSON format.
