Rails response to CQRS
View rails-response-to-cqrs.rb
# I have been recently exposed to Martin Fowler's CQRS concept and saw some implementations on .Net
# Like this http://www.codeproject.com/Articles/555855/Introduction-to-CQRS
# Disliked it as it brings a lot of noise in the code, a lot of handlers, class imbrications that defies simple human logic
# To say shortly, it's not quite cool, and as a rubyist I like keeping it simple and human
# Though the core concept of CQRS is quite simple, separate writes and reads to different database connections to increase global performance
# But implementation is very complex
# Lastly, someone I know even spent 2 years on a .Net project using CQRS (don't know how many weeks/months spend for just implementing the CQRS thing)
# I wrote this gist to see whether it can be done in 10 minutes
# And I did it in 10 minutes
# I love ActiveRecord so I DRYed by just extending it
You can’t perform that action at this time.
