but is it web scale?
Discussion
/s
if by web scale you mean Apple CloudKit and Snowflake scale, yes, actually
it in fact does not write your data to /dev/null
it is a KV store, which means you can build a lot, but also means you need to build your own architecture
perfect for nostr use cases
it struggles a bit with large values, but you can easily fix that by using SeaweedFS (some-maintenance-required FS that allows storing a lot of small files like 100KB)
