RoundRobin

Add a Round-Robin based process to your flow.

Installation

Add this line to your application's Gemfile:

gem 'roundrobin'

And then execute:

$ bundle

Or install it yourself as:

$ gem install roundrobin

Usage

>> Roundrobin.next(%w(foo bar))
=> "foo"
>> Roundrobin.next(%w(foo bar))
=> "bar"
>> Roundrobin.next(%w(foo bar))
=> "foo"

>> candidates = [{name: 'John', email: 'john@example.com'}, {name: 'Sara', email: 'sara@example.com'}])
>> Roundrobin.next(candidates) 
=> {name: 'John', email: 'john@example.com'}
>> Roundrobin.next(candidates)
=> {name: 'Sara', email: 'sara@example.com'}
>> Roundrobin.next(candidates) 
=> {name: 'John', email: 'john@example.com'}

All the data will be persisted to your DB, so you can restart your server, or do this in multiple threads and the results will be the same: you will be using the Round Robin algorith.

Development

$ cd roundrobin $ gem build roundrobin.gemspec $ gem install ./roundrobin-XXX.gem
