I moved some (important, but not critical) infrastructure off AWS SQS and Lambda to CF Queues and Workers. While less robust in many ways, the developer experience on Cloudflare is much better. Great job on building this out.
A few things I'd like to see added/improved:
1) The ability to requeue messages in the dead-letter queue
2) The ability to see message contents in the queue
3) A better local dev experience (I'd love to see something like the Firebase emulators for workers/KV/queues/etc)
But it's a very good beta so far.
