Cutting Down Rust Compile Times From 30 to 2 Minutes With One Thousand Crates (www.feldera.com)

Instead of emitting one giant crate containing everything, we tweaked our SQL-to-Rust compiler to split the output into many smaller crates. Each one encapsulating just a portion of the logic, neatly depending on each other, with a single top-level main crate pulling them all in.

Impressive improvement! But why did they choose Rust to compile on demand in the first place, if compile time was that important?
