Enum MetadataCompactionLeaseStatus 

pub enum MetadataCompactionLeaseStatus {
    Active,
    Reaping,
}

Lifecycle of a compaction lease: two states and one transition.

A lease is created active by the job that owns the prefix. Garbage collection moves it to reaping by compare-and-swap once it has expired, and that transition is the fence: the worker’s next heartbeat compare-and-swap fails, so it can never publish, and only then may the collector treat the prefix as orphaned. reaping is terminal — nothing returns a lease to active, and the collector deletes the object once the prefix’s unreferenced segments are gone.

Variants

Active

The job owns its prefix. Whether it is still running is a question about heartbeat_at_ms, not about this field.

Reaping

Terminal: garbage collection claimed the prefix, so the job that wrote it is fenced and the objects under it are orphans.
