Welcome back to More Than a Refresh Presents: T3D Sessions.In this episode, Joshua “JD” Drake talks with Lev Kokotov, creator of PGDog, about one of the hardest problems in PostgreSQL: horizontal scaling in real production systems.Lev shares lessons learned from scaling Postgres at Instacart during periods of extreme growth, and why existing approaches often fail when applied to large, established applications. They explore what happens when rewriting millions of lines of code simply isn’t an option—and why tooling needs to adapt to applications, not the other way around.
