Used in conjunction with cluster connections where you provide a preference about what state a node should be in.
There are three variants:
-
NodePreference.Leader When you prefer the node you connect to is in a VNodeState.Leader state. This is, for instance, used when you wish to avoid unecessary network hops when appending data.
-
NodePreference.Follower When you prefer the node you connect to is in a VNodeState.Follower state. This is useful in situations where you wish to get fast subscription updates for a read model.
-
NodePreference.ReadOnlyReplica When you prefer the node you connect to is in a VNodeState.ReadOnlyReplica or VNodeState.ReadOnlyLeaderless state. This is useful when you wish to replicate data, but do not have requirements for fast updates or need to append data.
