pub fn upgrade(
_snapshot: Vec<StateUpdateKind>,
) -> Vec<MigrationAction<StateUpdateKind, StateUpdateKind>>Expand description
No-op migration. Every v87->v88 change is additive and confined to the
append-only audit log: new CreateOrDropClusterReplicaReasonV1 reasons
(Reconfiguration, HydrationBurst, Retired) and new
AlterClusterReconfigurationV1 / ClusterHydrationBurstV1 event details.
No existing record changes shape, so a v87-serialized record is already
valid v88 and nothing is rewritten.
