       | Vitess/PlanetScale? I'm guessing weaker than read-your-writes.

       | Not directly related, I've been really tempted by all these
       | exciting new database offerings.. PlanetScale, CockroachDB,
       | FaunaDB.. but there don't seem to be any solid (node.js)
       | background job queue libraries that support them. I really want
       | to take advantage of these low dev-ops high availability
       | offerings, but I don't want to have to tack Redis onto my stack
       | just so I can use BullMQ, with data persistence and robustness as
       | a bit of an afterthought.
       | 
       | And I don't want to roll my own because it's not a trivial thing
       | to solve, especially with stall detection etc.
       | 
       | I'd love to just have one robust data-store.
       | 
       | Am I missing something?

         | Yeah... I wish Temporal had FaunaDB support. Seems like a great
         | fit for globally distributed jobs.

           | It sounds like temporal supports CockroachDB

           | Temporal sounds _very_ interesting, hadn't heard of it
           | before..

       | This would be such a nice addition to apps deployed on fly.io

         | Author here. Funny you mentioned that, we worked with the
         | Fly.io team to get this guide created for just that:

       | What kind of consistency guarantees does this offer?
