Show HN: Shelver, document store using cloud storage providers

When using ephemeral cloud servers (Cloud Run, Lambda functions, etc), I often find myself wanting a quick and easy database to persist data. I've found cloud storage to be the best place for this but wanted a unified API between providers. I also wanted to be able to build an object on the server before persisting to the storage provider, so I came up with this approach.

What other approaches are people using for this problem?

Really cool. I always wondered if something like this exists but could never find anything. Things like minio are quite different as they don't use the cloud native storage.

Amazing, one more step towards breaking vendor lock in!
