Please add possibility to read from zip or gzip/tar.gz compressed files for CSV data files used by CSV Data Set Config element. This will help to deal with MB or GB data files in the environments with quota restrictions or smaller storage purchased. If possible, also add the property to switch between logging to common files and compressed files when testing is ongoing. Again, this makes difference for server-hours like testing with big amount of transactions logged, moving storage requirement to 10x less then it is now.
