Enum ReplayGuarantee

Source

pub enum ReplayGuarantee {
    NonDeterministic,
    Deterministic,
}

Expand description

How faithfully a Source replays its record stream when resumed from a bookmark.

This is the source-side capability the effectively-once atomic-watermark mechanism depends on: after a crash the pipeline re-anchors the source at a persisted position, and correctness requires that nothing before that position is re-emitted and nothing after it is skipped.

Variants§

§

NonDeterministic

Resuming from a bookmark may replay a different record stream (query-based sources whose upstream can mutate, sources without per-page bookmarks). The default.

§

Deterministic

The source emits a complete resume position (bookmark) on every page, and resuming from any such bookmark continues the record stream at exactly that position — no record before the bookmark is re-emitted and none after it is skipped (immutable-log sources: CDC WAL/binlog/ change streams, Kafka partitions).
