Batch

Struct Batch 

Source
pub struct Batch {
    pub position: Option<Position>,
    pub changes: usize,
    pub envelopes: Arc<[Envelope]>,
}
Expand description

The envelopes one ingest commit built, in build order, with the position of the last change the batch covers. A live batch with no envelopes (every change resolved to nothing this sink indexes) still carries its position, so acknowledging it moves the watermark. A snapshot batch carries none.

The envelopes are shared, not owned: one build is published to every lane and held for redelivery without copying the documents, so a batch is immutable once built — a sink stamps nothing into it.

Fields§

§position: Option<Position>

The position of the last change in the batch; None for snapshot rows.

§changes: usize

How many source changes the batch was built from, for progress accounting; 0 for a snapshot batch.

§envelopes: Arc<[Envelope]>

The documents, in build order.
