Better CSV processing with Ruby 2.6

csv, one of the standard libraries, in Ruby 2.6 has many improvements:

  • Default gemified
  • Faster CSV parsing
  • Faster CSV writing
  • Clean new CSV parser implementation for further improvements
  • Reconstructed test suites for further improvements
  • Benchmark suites for further performance improvements

These improvements are done without breaking backward compatibility.

This talk describes details of these improvements by a new csv maintainer.
