For times when you need distributed generation, I’ve worked with a system that I liked. Server kept track of a sequence. Clients pull out batches of 1000 or so and then use them up. When the client starts to get low on available numbers it fetches another batch. The ids generated are nice readable integers. Generally in sorted order, though not a guarantee, and you end up with gaps sometimes if a client doesn’t give out all its numbers before it’s restarted. Would anyone be interested in a super robust version of that as a service?
