- Each parameter is checked for type and normalized - Interval strings are converted to DateInterval objects - Timeouts can be specified as interval strings - Most intervals can be null to signify infinity - Driver classes are checked that they implement the correct interface - Short driver names may be used, and are used by default - Helpful errors messages are printed in case of erroneous configuration Exporting is currently broken; this will be fixed in an upcoming commit
