Sidekiq allows specifying behavior when there is an exception. You can choose to use the default exponential backoff algorithm. I needed a way to change the backoff to be slower and more random. The exact backoff algorithm can be anything.
class YourWorker
include Sidekiq::Job
sidekiq_retry_in do |count, exception, jobhash|
case exception
when ::Faraday::TooManyRequestsError
5.minute.to_i + rand(10000)
end
end
end
I also wanted to test it. Found the simplest way is to just call the block and test that behavior which is what the author of Sidekiq recommends.
describe "Sidekiq retry in block" do
subject { YourWorker }
let(:exception) do
Faraday::TooManyRequestsError.new("Too many requests")
end
it "queues between 5...172 minutes" do
expect(
subject.sidekiq_retry_in_block.call(0, exception, {})
).to be_between(300, 10300)
end
end
