The schema:

    CREATE TABLE IF NOT EXISTS users (
        id BLOB PRIMARY KEY NOT NULL,
        created_at TEXT NOT NULL,
        username TEXT NOT NULL
    );

The data:

    let user = User {
        id: uuid::Uuid::new_v4(),
        created_at: chrono::Utc::now(),
        username: String::from("Hello"),
    };

If you can't insert 15,000 of these records per second then there's something wrong with your database. I'm aware that people are all on the SQLite hype train, but this kind of stuff is table-stakes.

I really like SQLite. But this blog isn't any kind of great performance indicator for it.
