To connect to Cassandra, you can use either a DSN or an ODBC connection string. Both of these methods use the Database's Open method.

Connect to a DSN

To connect using a DSN:

var db = new Database();
db.open("DSN=CData Cassandra Sys", (err) => {
    // Use the connection
});

Provide a Driver Connection String

To connect using an ODBC connection string:

var db = new Database();
db.open("DRIVER={CData ODBC Driver for Cassandra};Database=MyCassandraDB;Port=9042;Server=127.0.0.1;;", (err) => {
    // Use the connection
});
