I'm using workers since beta, including KV storage, it's great overall. Unfortunately recently noticed (testing for production launch) that there are rate limits in place (something around 2k requests per minute per IP for requests that go trough to origin server) - known issue it seems - https://community.cloudflare.com/t/rate-limit-on-workers/49548 https://community.cloudflare.com/t/rate-limit-on-workers/495... . I've contacted support already, ticket is marked as 'solved' but I still experience limits (429/1015 error codes). I'd love to know if it's something to be expected and if someone is planning to run tens or even hundred requests per seconds from single IP (I have bit weird API to work with that requires that) it's better to not use workers as it's not intended scenario? Or it's a matter of having more expensive Cloudflare plan (I'm on 5$/month for workers)? Would really appreciate more details on that subject as can't really change that API and will constantly run into 429 errors.
