The Changelog: Software Development, Open Source

Postgres at PlanetScale (Interview)

Sam Lambert is back after 4 years and he does not hold back! We cover $5 PlanetScale Postgres, the Neki “do-over” of Vitess, agents shipping schema changes through deploy requests, rolling back a 500TB table in seconds, and the very real question of whether to open source any of it. Plus: why he thinks the sleeping, lazy giants should be broken up.
