Initialize a DataStax Enterprise (DSE) cluster
To deploy DataStax Enterprise (DSE), you must initialize the cluster, including datacenters, racks, and nodes. Then, install DSE on the nodes.
|
DataStax recommends deploying a test cluster and running performance tests with simulated production workloads before rolling out a full-scale production deployment. |
Review the deployment process and plan your clusters to minimize the chance of unintended misconfiguration or downtime:
-
Understand how DSE works:
-
Ensure the environment is suitable for your use case and workload:
-
Understand hardware requirements and recommended settings before initializing the cluster:
-
For a mixed-workload cluster, determine the purpose of each node, and whether to use a single datacenter or multiple datacenters.
This is critical if you plan to use DSE advanced workloads, such as DSE Search or DSE Analytics.
-
Choose a snitch and replication strategy.
The GossipingPropertyFileSnitch and NetworkTopologyStrategy are recommended for production environments.
-
Using the information you gathered in the previous steps, deploy your cluster and nodes on your preferred infrastructure.
-
Get the cluster name and the IP address of each node.
-
Install DSE on each node.
You might need to restart DSE multiple times as you complete the initial configuration.
-
Determine which nodes are seed nodes, and then configure your cluster accordingly.
Don’t make all nodes seed nodes.
Seed nodes aren’t required for DSE Search datacenters.
-
Review and modify other property files as needed.
-
Set virtual nodes (vnodes) based on the type of datacenter.
DataStax recommends using 8 vnodes (tokens).
If not using vnodes, see Calculating tokens for single-token architecture nodes.
-
Connect to your cluster using APIs and clients, such as Apache Cassandra drivers.
These are essential connections for application development with DSE.
-
Before deploying clusters in your production environment, run performance tests with simulated production workloads to validate your cluster configuration.
Modify the configuration and retest until the cluster meets your performance requirements.
