Steady

This gem is aimed at helping speed up ruby webapps by putting reoccuring but non time critical tasks into a background thread. It aids with the periodic scheduling as well as the threading issues that arise from moving data between threads.

Example

Scheduler = Steady::Scheduler.new

Scheduler.every 3.seconds do |changes|
  changes[:plans] = JSON.parse(open("http://mysite.com/plans.json")) 
end 

# Run all above tasks now to get initial data
Scheduler.run 

# Schedule a thread to do this periodically
Scheduler.schedule


# Access your data in a thread safe manner 
Scheduler.data[:plans]
