All Implemented Interfaces:
RaftEntry
public record ConfigurationEntry(long timestamp, Collection<RaftMember> members) extends Record implements RaftEntry
Stores a cluster configuration.

The ConfigurationEntry stores information relevant to a single cluster configuration change. Configuration change entries store a collection of members which each represent a server in the cluster. Each time the set of members changes or a property of a single member changes, a new ConfigurationEntry must be logged for the configuration change.
