There are some semantic differences compared to POSIX filesystems. A couple big ones:

  - You can only append to an object, and each object can only have one writer at the time. This is useful for distributed systems - you could have one process adding records to the end of a log, and readers pulling new records from the end.
  - It's also possible to "finalize" an object, meaning that it can't be appended to any more.

(I work on Rapid storage.)

Slight nit: "zonal" doesn't necessarily mean "not replicated", it means that the replicas could all be within the same zone. That means they can share more points of failure. (I don't know if there's an official definition of zonal.)

NB: I am on the rapid storage team.

No, not for GCP stuff.

I don't know of a single GCP product that's been shut down, although I could be missing something. But their track record for GCP is, I think, what you would want a cloud provider's record to be.

(I should mention that I work for GCP. But this is just based on my own memory.)

Got it, thank you! CockroachDB is the only one I know offhand that does what you're looking for. Another comment mentioned Vitess, which might also work.

It seems like there are a lot of options for large scale analytics, but I don't know a lot for high throughout geo-redundant transaction processing.

Spanner offers that on GCP, and I believe CockroachDB offers something similar cross-cloud.

Do you have any specific requirements for which cloud provider you use, or any particular interface you really need?

The solution is posting this marketplace on a forum full of people who might like to buy and sell side projects

I mean to be fair Google has also tried very, very hard to improve home internet access for people, to the point of setting up their own ISP and running municipal fiber networks. That's a pretty big try, and I really wish it had taken off beyond the places where Google Fiber operates.

(NB: I work at Google, but this comment has nothing to do with my work.)

Someone close to me has Celiac disease, and getting an official diagnosis will let you do more than just eliminate gluten. For one thing, you could participate in one of the multiple ongoing drug trials for Celiac that are looking for participants.

The Celiac foundation has a list of them if you're interested, but you'll need a Celiac diagnosis to be eligible.

I'd be curious to know what the libraries are that allow this sort of database engine design. Are there any open source examples?

Imagine if Barnes and Noble had done it, and you could drive to one of their stores to quietly sip a drink and peruse the new machines they had provisioned recently.
