How can we use waitUntil() in cloudflare workers with this rate limit.

Hi, I actually have two questions -

1. If we pass an already initialised upstash redis instance, is the same one used again or a new one is created?

export function getGlobalRedis(env: any): Redis {
  if (!globalRedis) {
    globalRedis = new Redis({
      url: env.UPSTASH_REDIS_REST_URL,
      token: env.UPSTASH_REDIS_REST_TOKEN,
    });
    console.log("🔄 Created global Redis connection");
  }
  return globalRedis;
}

2. Can we somehow not wait for PEXPIRE commands of (eg, FixedWindow) like by using waitUntil() in cloudflare workers? We only need to read synchronously to block requests?

Hi there,

1. Same one will be used.
2. It could be possible, but keeping the PEXPIRE in the same request is simpler I think. Because:
   • PEXPIRE doesn't always run, it only runs when we enter a new time window. So it shouldn't always cause latency.
   • There would have to be an additional request for PEXPIRE.
