Struct MetadataCompactionLeaseState 

pub struct MetadataCompactionLeaseState {
    pub job_id: MetadataCompactionId,
    pub namespace_id: NamespaceId,
    pub writer_id: String,
    pub status: CompactionLeaseStatus,
    pub started_at_ms: u64,
    pub heartbeat_at_ms: u64,
}

Records ownership of a streaming compaction’s output prefix.

The lease contains no cursor, output descriptor, or progress. The job refreshes it while running. Garbage collection claims an expired lease by compare-and-swap before reclaiming the prefix (format spec, “Garbage collection”, rule 12).

Fields

job_id: MetadataCompactionId

Job this lease belongs to, which is also the prefix its output sits under.

namespace_id: NamespaceId

Namespace whose family group the job is rebuilding.

writer_id: String

Writer identity the job runs under, for an operator reading the object. This is the same label the namespace head records.

status: CompactionLeaseStatus

Who owns the prefix: the job that wrote the lease, or the collector that claimed it.

started_at_ms: u64

Unix-millisecond stamp of the job’s first lease write.

heartbeat_at_ms: u64

Unix-millisecond stamp of the most recent lease write, and the only input to whether an active lease has expired.
