A stateless pattern I use to batch telemetry at the edge while driving Cloudflare write costs to zero.

  Cool pattern. Critics will say “falsehoods programmers believe about time” but it’s a cloud service, any time oddity that would break this would also break a lot more important stuff, so it’s fine.
  Ugly code though.
```
  // env
  QUEUES = [EVEN_QUEUE, ODD_QUEUE]

  // producers
  env.QUEUES[hour % 2].send …

  // consumer
  env.QUEUES[1 + hour % 2]
```
