Ractor report
This talk will introduce Ractor, the concurrency system for Ruby 3 based on actual implementation.
At RubyKaigi 2016, I proposed Guild (A proposal of new concurrency model for Ruby 3) and at RubyKaigi 2018, I introduced prototype of it (Guild Prototype - RubyKaigi 2018). For Ruby 3, we renamed Guild to Ractor and finished the first implementation. This talk will introduce Ractor API with current implementation.
