  Interesting, tweaking sounds like a very minimal intervention. I’d imagine this would need to be refactored but then maybe things are different in Rust.

  “Instead of emitting one giant crate containing everything, we tweaked our SQL-to-Rust compiler to split the output into many smaller crates.”

  It seems a bit weird the developer has a 64 core machine and suddenly realises the cores are dormant.

  I was expecting some DAG set up, and it motors its way through to the end.
