Connect an Application¶

To connect your application to ScyllaDB, you need to:

1. Install the relevant driver for your application language.

   This step involves setting up a driver that is compatible with ScyllaDB. The driver acts as the link between your application and ScyllaDB, enabling your application to communicate with the database.

2. Modify your application code to connect the driver.

   The following is some boilerplate code to help familiarize yourself with connecting your application with the ScyllaDB driver. For a detailed walkthrough of building a fictional media player application with code examples, please see our Getting Started tutorial.

use anyhow::Result;in various languages
use scylla::{Session, SessionBuilder};
use std::time::Duration;
#[tokio::main]
async fn main() -> Result<()> {
    let session: Session = SessionBuilder::new()
        .known_nodes(&[
            "localhost",
        ])
        .connection_timeout(Duration::from_secs(30))
        .user("scylla", "your-awesome-password")
        .build()
        .await
        .unwrap();

    Ok(())
}

func main() {
    cluster := gocql.NewCluster("localhost")

    cluster.Authenticator = gocql.PasswordAuthenticator{Username: "scylla", Password: "your-awesome-password"}

          session, err := gocqlx.WrapSession(cluster.CreateSession())

          if err != nil {
                    panic("Connection fail")
          }
 }

import com.datastax.driver.core.Cluster;
import com.datastax.driver.core.PlainTextAuthProvider;
import com.datastax.driver.core.Session;

class Main {

    public static void main(String[] args) {
    Cluster cluster = Cluster.builder()
        .addContactPoints("localhost")
        .withAuthProvider(new PlainTextAuthProvider("scylla", "your-awesome-password"))
        .build();

    Session session = cluster.connect();

    }
}

from cassandra.cluster import Cluster
from cassandra.auth import PlainTextAuthProvider
cluster = Cluster(
    contact_points=[
        "localhost",
    ],
    auth_provider=PlainTextAuthProvider(username='scylla', password='your-awesome-password')
)

const cluster = new cassandra.Client({
    contactPoints: ["localhost", ...],
    localDataCenter: 'your-data-center',
    credentials: {username: 'scylla', password: 'your-awesome-password'},
    // keyspace: 'your_keyspace' // optional
