SQLite's hidden VM becomes the LLVM of databases, courtesy of Turso

SQLite has run a virtual machine called VDBE under the hood for 25 years, compiling SQL into linear bytecode. Turso is turning that hidden implementation detail into a public intermediate layer—a database LLVM. Their Rust-based pgmicro already parses Postgres SQL and emits VDBE bytecode, and they proved the VM's general-purpose chops by running Doom inside the engine. The hard part ahead is Postgres extension compatibility; compiling extensions to WASM is still a PoC.

Why it matters: Solid technical depth with an insightful VDBE-as-LLVM analogy, but the topic leans toward database internals, a bit removed from the daily concerns of AI practitioners. H and K both hit, R is weak, lands right at the featured threshold.
