CQL console

The Cassandra Query Language SHell (CQLSH) is a command line shell for interacting with your database through Cassandra Query Language (CQL). This tool provides a useful interface for accessing the database and issuing CQL commands.

Embedded Astra DB CQL shell

Each DataStax Astra DB database includes an embedded CQL shell instance. In the Astra DB console, navigate to your database and click the CQL Console tab to open a CQLSH instance that is connected to your database. Issue CQL commands directly to your Astra DB database without navigating outside of your browser.

To see the CQL console in a full browser window, use this URL format:

database_id-region.apps.astra.datastax.com/cqlsh

For example, 2f0c6j8b-9790-4276-a16c-0cd7b055344a-us-east1.apps.astra.datastax.com/cqlsh

Once you open the CQL shell in Astra, you will automatically be signed in and connected to your database.

Results

You can now run CQL commands in your embedded CQL shell.

Alternatively, you can connect to your Astra DB database using the standalone version of CQLSH.

Standalone CQL shell

Instead of using the native CQL shell that is included in DataStax Enterprise (DSE), the standalone CQLSH client is a separate, lightweight tool you can use to interact with your database.

Each DataStax Astra DB database includes an embedded CQL shell instance. In the Astra DB console, navigate to your database and click the CQL Console tab to open a CQLSH instance that is connected to your database.

Prerequisites

  1. Download CQLSH. Choose the version for Astra DB.

  2. Create an Astra DB database.

Working with secure connect bundle

Downloading secure connect bundle

To connect to your Astra DB database using the drivers, download the secure database bundle from the DataStax Astra DB console that contains the connection credentials.

  1. Open a browser, navigate to Astra DB, and log in.

  1. From your Dashboard page, select your database.

  1. On the Overview page, select Connect.

  1. In the Connect using a driver section, click your preferred language from the list to load language-specific instructions.

    If you have multiple regions, select the region you want to connect to from the dropdown menu for instructions.

Note, though, that the bundle URL is the same for all languages.

  1. Click Download Bundle.

    If you have multiple regions, you will have the option to download a bundle for each region from the expanded Download Bundle drop-down menu.

If you’ve enabled VPC peering, you can also Download External Secure Connect Bundle for use within your VPC peering. The secure-connect-database_name.zip file downloads, which contains the security certificates and credentials for your database.

VPC peering is only available on Classic databases.

Alternatively, you can right-click the Download credentials link, copy the link source, and then use a curl command to download the secure-connect-database_name.zip file:

curl -L "<secure-connect-database_name-download-URL>" > database_name.zip
Sharing secure connect bundle

Although teammates can access your Astra DB database, it will not display in their list of available databases under My Databases in the Astra DB console.

After you create an Astra DB database, you can grant access to other members of your team by providing them with the database credentials and connection details for your database.

Be careful when sharing connection details. Providing this information to another user grants them access to your Astra DB database and ownership capabilities, such as making modifications to the database.

For security, delete downloaded connection credentials after sending them to your teammate.

Procedure

  1. Change to the directory where you downloaded the CQLSH tarball and then extract it:

$ cd /<download_directory>
$ tar -xvf cqlsh-astra-<date>-bin.tar.gz
  • date - The date that the tarball was released, such as 20210304.

  1. From the directory where you extracted the CQLSH tarball, run the cqlsh script from the command line:

$ cd /cqlsh-astra
$ ./bin/cqlsh -u **clientID** -p **clientSecret** -b /path/to/secure-connect**database_name**.zip

Use the -b option to specify the location of the secure connect bundle that you downloaded for your database. Pass the Client Id and Client Secret for your database role using the -u and -p options. For more, see Manage application tokens.

  • username - Client ID for the database role.

  • password - Client secret for the specified Client ID.

  • database_name - Name of the Astra DB database to which you want to connect. Include the absolute path to the secure connect bundle for the database, such as /Users/myuser/Downloads/secure-connect-database123.zip.

Configure the cqlshrc file If you do not want to pass the secure connect bundle on the command line every time, set up the location in your cqlshrc file.

In the [authentication] section of the cqlshrc file in ~/.cassandra, include the Client ID and Client Secret from your application token. Configure the [connection] section of the cqlshrc file in ~/.cassandra to include the path to your secure connect bundle.

[authentication]
username = clientID
password = clientSecret

[connection]
secure_connect_bundle = **/path/to/**secure-connect-**database_name**.zip

Results

You are connected directly to your database using CQLSH.
