Expand description

Events produced by the FailoverCoordinator during each tick.

Variants§

§

LeaderLost

The current leader has been detected as failed and an election has been scheduled (after the jitter delay expires).

Fields

§old_leader: NodeId

Node ID of the old leader.

§election_triggered: bool

Whether an election timer was started as a result.

§

LeaderElected

A new leader has been acknowledged (set via FailoverCoordinator::set_leader).

Fields

§new_leader: NodeId

Node ID of the new leader.

§

FailoverTimeout

The election jitter timer expired without a new leader being set.

§

PeerFailed

A non-leader peer has failed.

Fields

§node_id: NodeId

The failed peer.

§

PeerRecovered

A previously-failed peer has recovered.

Fields

§node_id: NodeId

The recovered peer.
