Struct TopKRefill

Source

pub struct TopKRefill {
    pub rows: Vec<TopKCandidate>,
    pub payload: RecordBatch,
    pub unseen_bound: Option<u64>,
}

Expand description

The next batch of a tablet’s local top-k (adaptive refill, spec section 12.10).

Fields§

§rows: Vec<TopKCandidate>

The next local candidates (rows not returned before, best first), aligned with payload’s rows.

§payload: RecordBatch

The candidates’ full row payload (same schema as the stream output).

§unseen_bound: Option<u64>

Tightened unseen-score bound (None = tablet exhausted).
