ScyllaDB Seed Nodes¶
A ScyllaDB seed node is a node specified with the seeds
configuration parameter in scylla.yaml
. It is used by new node joining as the first contact point.
It allows nodes to discover the cluster ring topology on startup (when joining the cluster). This means that any time a node is joining the cluster, it needs to learn the cluster ring topology, meaning:
What are the IPs of the nodes in the cluster are
Which token ranges are available
Which nodes will own which tokens when a new node joins the cluster
Once the nodes have joined the cluster, the seed node has no function.
The first node in a new cluster must be a seed node. In typical scenarios, there’s no need to configure more than one seed node.
