Struct DrainStats 

Source 
pub struct DrainStats {
    pub applied: usize,
    pub stale_epoch: usize,
    pub duplicates: usize,
    pub unknown: usize,
}
Expand description

Counters from one Checkpointer::drain call, for metrics.

Fields§

§applied: usize

Resolutions applied to a tracker.

§stale_epoch: usize

Registrations or resolutions discarded because their epoch is not current or their partition is not assigned (normal after rebalance).

§duplicates: usize

Duplicate resolutions (already resolved or already advanced).

§unknown: usize

Resolutions that never found a registration — driver bug.
