Node

A node is the basic unit of organization for a ScyllaDB database. It is comprised of the ScyllaDB database server software running on a computer server.

Each ScyllaDB node contains a portion of the entire database cluster’s content and consists of several independent shards.

In ScyllaDB, all nodes are equal. There are no master or slave nodes, and each node can serve requests. All nodes work together to provide service even if one node becomes unavailable due to some failure.

Let’s check the status of the nodes that we just set up. To do that, we use a tool called Nodetool Status.

docker exec -it scylla-node3 nodetool status  

You’ll see that we have 3 nodes set up from the previous topic and that all the nodes have UN for status. U means up, and N means normal.
