Connection methods comparison

Connect to your Hyper-Converged Database database with a client or a CQL driver.

What’s the difference between a client and a driver?

Clients let you interact with the Data API. Drivers let you interact with CQL.

DataStax recommends that you use a client for most applications, as it’s an easier way to get started with Hyper-Converged Database. However, you should use a driver if you have a legacy application or want to take advantage of specific Cassandra features.

Use CQL Proxy to connect with an unsupported driver

DataStax CQL Proxy simplifies connecting to Hyper-Converged Database without having to change your Cassandra driver, driver version, and/or framework (springdata, lagom, akka-persistence-cassandra, quarkus, etc.). This open source tool securely forwards your application’s CQL traffic to an appropriate database service. CQL Proxy auto-discovers and auto-configures communication with Hyper-Converged Database.

If you are using a driver for an unsupported language, consider using CQL Proxy. The CQL Proxy sidecar enables unsupported CQL drivers to work with Hyper-Converged Database.
