To connect to ScyllaDB Cloud Serverless, download the connection bundle YAML from the Connect tab in the Cloud console and pass it as the scylla_cloud parameter when constructing the Cluster object. Do not point the driver at a hostname and port the way you would for a self-hosted cluster; the bundle carries the endpoints and credentials. Keep the bundle file out of version control since it contains credentials.

Context: ScyllaDB Python driver docs (ScyllaDB Cloud Serverless): documents the gotcha that connecting to a ScyllaDB Cloud Serverless database does not work with a plain host and port like a self-hosted cluster. The driver needs the connection bundle YAML downloaded from the Cloud console's Connect tab, passed as the scylla_cloud parameter to Cluster. Agents that hardcode contact points will fail to connect.
