From a long time ago, but the (impressive!) leaderboard still has the same order (the Rust implementation did get faster!).
[Wayback/Archive] Towards Inserting One Billion Rows in SQLite Under A Minute – blag
Recently, I ran into a situation where I needed a test database with lots of rows and needed it fast. So I did what any programmer would do: wrote a Python script to generate the DB. Unfortunately, it was slow. Really slow. So I did what any programmer would do: went down the rabbit hole of learning more about SQLite, Python, and eventually Rust… in my quest to get a 1B row database under a minute. This blog post is a summary of this fun and educational exercise.
