connection_pool

Generic connection pooling for Ruby.

MongoDB has its own connection pool. ActiveRecord has its own connection pool. This is a generic connection pool that can be used with anything, e.g. Redis, Dalli and other Ruby network clients.

Install

gem install connection_pool

Usage

Create a pool of objects to share amongst the fibers or threads in your Ruby application:

@memcached = ConnectionPool.new(:size => 5, :timeout => 5) { Dalli::Client.new }

Then use the pool in your application:

@memcached.with do |dalli|
  dalli.fetch('some-count', :expires_in => 1.day) do
    SomeModel.query.count
  end
end
