Similar to Single-page applications (SPA), single-table application (STA) might become a thing. Just a shard a table on multiple keys and serve the shards as static files, provided that the data is Ok to share, similar to sharing static html content.

And the important lesson from that the k/v-like aspect of it. That the "schema" is horizontal (is that a thing?) and not column-based. But I actually only read it on their blog IIRC and never even got the full details - that there's still a third ID column. Thanks for the link.
