How to Use Rust for ETL/Data Pipelines

Build fast, concurrent ETL pipelines in Rust using the tokio runtime and async/await syntax for efficient data processing.

Use Rust's tokio runtime with async/await to build high-performance, concurrent ETL pipelines that process data streams efficiently.

use tokio::io::{AsyncBufReadExt, BufReader};
use std::fs::File;

#[tokio::main]
async fn main() -> std::io::Result<()> {
    let file = File::open("input.csv")?;
    let reader = BufReader::new(file);
    let mut lines = reader.lines();
    
    while let Some(line) = lines.next_line().await? {
        let processed = line.to_uppercase();
        println!("{}", processed);
    }
    Ok(())
}
