| ApplyCommitRequest |
A master node sends this request to its peers to inform them that it could commit the
cluster state with the given term and version.

| CoordinationMetadata.Builder |
|
| CoordinationMetadata.VotingConfigExclusion |
|
| CoordinationMetadata.VotingConfiguration |
A collection of persistent node ids, denoting the voting configuration for cluster state changes.
|
| CoordinationState |
The core class of the cluster state coordination algorithm, directly implementing the
formal model |
| CoordinationState.VoteCollection |
A collection of votes, used to calculate quorums.

| DetachClusterCommand |
|
| DiscoveryUpgradeService |
Deals with rolling upgrades of the cluster coordination layer.
|
| ElectionSchedulerFactory |
It's provably impossible to guarantee that any leader election algorithm ever elects a leader, but they generally work (with probability
that approaches 1 over time) as long as elections occur sufficiently infrequently, compared to the time it takes to send a message to
another node and receive a response back.
|
| ElectionStrategy |
Allows plugging in a custom election strategy, restricting the notion of an election quorum.
|
| FollowersChecker |
The FollowersChecker is responsible for allowing a leader to check that its followers are still connected and healthy.

| Join |
Triggered by a StartJoinRequest, instances of this class represent join votes,
and have a source and target node. |

| LagDetector |
A publication can succeed and complete before all nodes have applied the published state and acknowledged it; however we need every node
eventually either to apply the published state (or a later state) or be removed from the cluster.
|
| LeaderChecker |
The LeaderChecker is responsible for allowing followers to check that the currently elected leader is still connected and healthy.
