Creating a connection in DataStax Studio

  • DSE 5.1 installed, configured, and running.

  • DataStax Studio installed and running.

  • If using DSE Graph, it must be configured and running.

A connection to a DSE cluster is required.

Each notebook has only one connection. Each connection can have multiple notebooks.

You can configure more than one host in a Studio connection. Hosts initialize the Cassandra driver connection, so more than one host provides redundancy and failover protection.

A notebook persists its data to a DSE cluster.

DSE Graph

The connection identifies a particular graph.

For notebooks using DSE Graph, the connection must be changed to use a different graph.


The connection identifies a database instance.

For notebooks using CQL, the keyspace and table can be changed within the notebook.

  1. To create a connection from a notebook to a DSE cluster:

  2. Browse to the URL for the Studio installation.

    $ http://URI_running_DSE:9091/
  3. In the menu (☰), select the Connections menu item.

  4. Create the connection from a notebook to a DSE cluster:

    1. Select Add connection (the plus icon in the top center of the page).

      The Create Connection dialog appears.

    2. Enter the connection information:


Name of the connection.

Host/IP (comma delimited)

The host names or IP addresses of the DSE cluster to connect to. Default: localhost.


Optional. DSE username for logging in.


Optional. DSE password for logging in.


IP connection port of the DSE cluster. Default: 9042.

This example connects to a single-node DSE cluster on the local host using the default port.


My First Connection




  1. Select Save.

    1. Click Test to verify the connection works.

    2. To configure a secure encrypted connection, select the Use SSL check box.

      The Truststore and Keystore fields display. See Using SSL connections in DataStax Studio.

    3. Click Save.

      A connection is created from the notebook to the DSE cluster.
