Connection methods comparison
Connect to your Astra DB Serverless database with a client or a CQL driver.
You have a legacy application that already uses CQL.
You need your collections to have a strict schema.
You don’t want all fields to be indexed.
If none of these conditions apply to you, use a client.
DataStax CQL Proxy simplifies connecting to Astra DB Serverless 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 Astra DB Serverless.
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 Astra DB Serverless.
