phat
Asynchronous Rails!
Phat
An asynchronous sample Rails app designed to run in thin.
Phat comes pre-configured to use Fiber-enabled asynchronous libraries for maximum scalability: em_postgresql, memcache-client and em-resolv-replace.
Usage
You must be running Ruby 1.9.x.
You'll need to initialize the application's gem bundle:
gem install bundler
bundler install --relock
Now just start the server:
thin -D start
Caveats
The Rails database rake tasks do not use EventMachine. Because of this, em_postgresql will fall back to blocking behavior if EM is not running.
The Rails 2.3.5 database rake tasks hard code the supported list of adapters such that "em_postgresql" is not supported. You will need to edit rails-2.3.5/lib/tasks/databases.rake and change all instances like so:
-
when "postgresql"
-
when /postgresql/
