This is essentially a re-explanation of Neon’s architecture as a blog post.

Amazing that the Postgres ecosystem got this software for “free” (as in at least a basic version of it is F/OSS, IIRC there wasn’t any core bits held back), and the extremely engineer-heavy company got to make money, AND they got bought out in true acquisition style by a larger player that truly benefits from the tech.

The Postgres ecosystem is pretty unique in its ability to produce a “boring” stable product, innovate, stay F/OSS, and create financial outcomes for participants.
