public class AppendRequest
extends AbstractRaftRequest

Append entries request that represent old version (version = 1) which only replicated the raft entry and not the complete serialized journal record.

Append entries requests are at the core of the replication protocol. Leaders send append requests to followers to replicate and commit log entries, and followers sent append requests to passive members to replicate committed log entries.
