[ANN] ARFFFiles.jl

I recently tagged version 1.0 of ARFFFiles.jl, a package for loading and saving data files in the Attribute Relation File Format.

This version introduces saving functionality, stabilises the API and adds a few performance tweaks.


Thank you, I did not realised that package existed, and it will be very useful for me :slight_smile: .

Version 1.2.0 has just been released.

  • Now supports UTF-8 encoded files (previously only supported ASCII).
  • Much faster loading of files with many columns (tested on 27,000 columns).
  • A generally more forgiving parser.

I’ve just released version 1.3.0.

  • Super fast! About the same speed as CSV.jl on equivalent data. For thousands of columns, it is about 2x faster than CSV.jl.
  • Now supports the sparse row format.
  • Now supports the Tables.partition interface for efficiently iterating through chunks of large files.
