Node

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

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

In Scylla 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 of the nodes 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 call Nodetool Status.

docker exec -it Node_Z nodetool status  

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