Integrations

Rails

Convert limit errors into a HTTP status code. Use rack-berater or handle it directly:

class ApplicationController < ActionController::Base
  around_action :limit
  rescue_from Berater::Overloaded { head :too_many_requests }

  private

  def limit
    # limit users to 10 API calls per second
    Berater("ingress_limiter:#{user_id}", 10, :second) { yield }
  end
end

Sidekiq

Sidekiq Ent provides a framework for applying limits to Sidekiq jobs and automatically reschedules workers when limits are exceeded. Berater limiters can be used seamlessly within this framework by registering its error class.

# config/initializers/sidekiq.rb

Sidekiq::Limiter.errors << Berater::Overloaded
