How to fail an exceeded rate limit, instead of waiting?

[dhempy]

When I hit my rate limit, I don't just tip my toe over the line...I do it with style, with thousands of excess requests per second.

In this case, I don't want to queue them up, I just want them to fail. How can I do that? Is it safe to raise an exception within the block passed to limit_method?

Yes, it appears this works as expected. Here is what I ended up with:

    %i[flaky_api_get flaky_api_put flaky_api_post].each do |method|
      limit_method(method, rate: 4, interval: 1) do
        Rails.logger.error "Rate limiting Flakey request: #{method}"
        raise FlakyRateLimitSelf, "Rate limiting Flakey request: #{method}"
      end
    end

And out of paranoia, I tested it:

      it do
        Timecop.freeze do
          expect { 10.times { FlakyService.send(method_name) } }
            .to raise_error(Auth0RateLimitSelf, "Rate limiting FlakyService request: #{method_name}")
        end
      end
