Hi

Can you please guide me on how to create a database connection pool for high volume transactions? I also would like to know how to open a database connection without creating a new database file in case the there is no database file in which case it should return an error. Thanks

Regards Vijay

 let rb = Rbatis::new();
    // ------------choose database driver------------
    rb.init(
        rbdc_sqlite::driver::SqliteDriver {},
        "sqlite://?mode=memory",
    )
    .unwrap();

I wanted to know if there is something similar to Sqlite::database_exists. I dont want to create a database file every time I open a database connection in case there is no database file already created.
