  • Line parsing and field parsing based on Int or UnitRange field widths.
  • Ability to parse non-contigious fields.
  • Supports DataStream Source functionality to enable streaming into a DataFrame...or anything that implements Sink.
  • Robust missing value detection
  • Skip or parse malformed rows without terminating parsing
  • Custom header specifiction
  • Start of file row skipping
  • Autodetect column widths if there is a separator between them using scan function
