Seed nodes
It might be the case where the administrator adds two different nodes at a time, and during
gossip, none of them would have information about each other. Also, there might be cases
where DynamoDB would be partitioned into logical parts. To avoid such issues, Dy-
namoDB keeps seed nodes that would have static information about the cluster. Some
nodes from the cluster play the role of seed nodes. Seed nodes have all the information
about the membership, as the information is derived from an external service. All nodes ul-
timately reconcile the membership information with seed nodes, and this helps in solving
the previously mentioned problems.
