Module rebalance 

Dynamic vnode rebalance control plane. Dynamic vnode rebalance control plane.

Structs

RebalanceConfig

Tunables for the rebalance control plane.

Functions

audit_assignment_snapshot_authority

Audit a materialized assignment-drain outcome against the shared authority sequence. Ordinary assignments and still-draining transitions require no terminal decision.

spawn_rebalance_controller

Spawn the leader-gated rebalance controller. Runs on every node; leadership is re-checked after the debounce.

spawn_snapshot_watcher

Spawn the per-node snapshot watcher. Exits on shutdown.

startup_committed_assignment

Select the last committed assignment that a cluster process may adopt during startup. A draining head has not transferred ownership, so startup retains its audited predecessor.

wait_until_drained

Poll the durable assignment snapshot until me owns no vnodes (its state has been reassigned elsewhere) or deadline elapses. Returns true if fully drained. A version materialized from a drain is accepted only with its matching shared-authority decision; None therefore supports ordinary snapshots but fails closed for a drain finalization. Used by a draining node to know when it is safe to exit.
