Glauber Costa, co-founder and CEO of Turso, joins us to discuss libSQL, Limbo, and how they’re rewriting SQLite in Rust. We discuss their efforts with libSQL, the challenge of SQLite being in the public domain but not being open for contribution, their choice to rewrite everything with Limbo, how this all plays into the future of the Turso platform, how they test Limbo with Deterministic Simulation Testing (DST), and their plan to replace SQLite.
