Enum SinkGuarantee 

pub enum SinkGuarantee {
    AtLeastOnce,
    KeyedUpsert,
    AtomicWatermark,
}

The strongest delivery guarantee a Sink can uphold.

Variants

AtLeastOnce

Plain writes: a replayed page is written again. The default.

KeyedUpsert

The sink can dedup by key (write_mode: upsert with a configured key): re-applying a record with the same key converges instead of duplicating.

AtomicWatermark

The sink can commit a page’s rows and a commit token in one atomic transaction (Sink::write_batch_idempotent).
