That's awesome, your use case is perfect for region scoped persistent storage.
We're testing persistent storage privately with a few customers now and the results are exciting. My favorite is using minio as a private global s3 for caching.
I would be really interested in Fly if it abstracted persistent storage. An exciting use case to me would be something that doesn’t with “...for caching.”
I am building a search engine and this would let me derive your performance benefits using region-scoped databases and search indices.
