Connecting to Astra DB databases

All DataStax drivers have configuration file attributes, builder methods, or constructor parameters for pointing to the secure connect bundle. The database username and password are specified through the normal driver APIs for configuring a plain text authentication provider, or through using one of the convenience methods for username and password.

When using the secure connect bundle, the DataStax drivers automatically establish mutually authenticated TLS connections to the service. You do not have to unzip the secure connect bundle or supply contact points.

After establishing a connection the resulting session is optimally configured for interacting with your Astra DB database. It is possible (but not required) to use other advanced features, such as Speculative query execution and Execution profiles.

The DataStax driver documentation for your language contains getting started examples and API documentation. Upgrade to the latest minor version of your language’s driver to get the new Astra connection API.

For new applications and for testing, use the DataStax drivers for Cassandra:

For existing applications that use the deprecated DataStax Enterprise (DSE) drivers:

If you have tooling that currently works with self-managed deployments (Cassandra or DSE clusters), connecting it to Astra DB is simple:

The following table shows the configuration settings required to connect to a self-managed deployment or an Astra DB database.
