ScyllaDB Cloud Connection Setup
This skill guides users through connecting their application to a ScyllaDB Cloud cluster using the appropriate CQL driver.
Overview
Connecting to ScyllaDB Cloud requires:
- Cluster credentials — username, password, and node addresses from the ScyllaDB Cloud Console
- A ScyllaDB CQL driver — installed for the user's programming language
This is an interactive step-by-step guide. The agent detects the user's environment and provides tailored instructions.
Step 1: Verify the Cluster is Running
Ask the user to confirm they have a ScyllaDB Cloud cluster. If not, direct them to:
- Go to cloud.scylladb.com and log in (or sign up)
- Click New Cluster or Free Trial
- Choose AWS or GCP, configure region, instance type, and cluster name
- Whitelist their IP address
- (Recommended) Enable VPC Peering during cluster creation — it cannot be enabled later
- Click Launch Cluster and wait for provisioning
Step 2: Retrieve Connection Credentials
Guide the user to obtain credentials from the Cloud Console:
- Go to My Clusters → open the cluster
- Open the Connect tab
- Note the following:
- Node addresses (contact points) — e.g.,
node-0.your-cluster.cloud.scylladb.com - Port — typically
9042 - Username — default is
scylla - Password — shown on the Connect tab
- Datacenter name — e.g.,
AWS_US_EAST_1
- Node addresses (contact points) — e.g.,
Do not ask for or handle credentials directly — guide the user to retrieve them from the Console and store them securely (environment variables, secrets manager, etc.).
Step 3: Determine the Driver
Ask the user which programming language they are using so you can recommend the correct ScyllaDB CQL driver:
| Language | Driver | Package |
|---|---|---|
| Python | scylla-driver | pip install scylla-driver |
| Java | java-driver (4.x recommended) | Maven/Gradle dependency |
| Go | gocql + gocqlx | go get github.com/scylladb/gocql |
| Rust | scylla-rust-driver | cargo add scylla |
| C# | scylla-csharp-driver | NuGet package |
| C++ | cpp-rust-driver | Build from source or vcpkg |
| Node.js | scylla-node-driver | npm install @scylladb/driver |
⚠️ Important: ScyllaDB has its own driver forks — do not use the DataStax/Cassandra drivers - unless there's no ScyllaDB driver available for your language. ScyllaDB drivers include shard-aware optimizations that route requests directly to the correct CPU core, improving throughput and latency.
Step 4: Configure the Connection
Consult references/driver-configuration.md for per-language connection snippets.
Critical requirements for ScyllaDB Cloud:
Authentication — PlainTextAuthProvider with the username and password from Step 2.
Consult references/cloud-connection.md for details on IP allowlisting and VPC peering.
Step 5: Test the Connection
Provide a minimal test query for the user's driver language:
SELECT release_version FROM system.local;
If this query returns a version string, the connection is working. If it fails, check:
- IP not allowlisted — verify the client IP is in the cluster's Allowed IPs list
- Wrong datacenter name — must match exactly (e.g.,
AWS_US_EAST_1, notus-east-1) - Wrong port — ensure port 9042 is used
- Firewall/VPN blocking — ensure outbound TCP on port 9042 is allowed
- Using Cassandra driver instead of ScyllaDB driver — the DataStax drivers lack shard-aware routing and may have compatibility issues
Step 6: Next Steps
Once connected, suggest relevant next steps:
- Data modeling: Use the
scylladb-data-modelingskill for schema design guidance - Vector search: Use the
scylladb-vector-searchskill if they need similarity search - Prepared statements: Recommend using prepared statements for all frequently-run queries (reduces parsing overhead, enables token-aware routing)
- Connection pooling: ScyllaDB drivers handle pooling internally with shard-aware connections — typically no manual tuning needed
- ScyllaDB Cloud MCP server: If the user wants to manage their ScyllaDB Cloud cluster programmatically via an AI agent (create clusters, monitor health, configure networking, etc.), the ScyllaDB Cloud MCP server is available.
