Expand description

Public, stable JSON shape for the run manifest.

One manifest is written per run_id per export. See ADR-0012 M4 (Append-Only Per Run) for the resume-across-interruption story.

Fields§

§manifest_version: u32§run_id: String§export_name: String§started_at: String§finished_at: String§status: ManifestStatus§source: ManifestSource§destination: ManifestDestination§format: String§compression: String§schema_fingerprint: String

xxh3 fingerprint of the column schema; see crate::state::schema_fingerprint.

§row_count: i64§part_count: u32§parts: Vec<ManifestPart>§column_checksums: Option<Vec<ColumnChecksum>>

Per-column value checksum over the whole export (Form B), keyed by column name — the per-column xxh3 XOR-combined over the run. rivet validate re-reads the parts and recomputes this to catch an Arrow→Parquet encode fault or post-write corruption — the step the in-process Form A check cannot see. Optional for back-compat: older manifests omit it (no MANIFEST_VERSION bump), newer readers tolerate its absence.

§checksum_key_column: Option<String>

The column the Form B checksum is keyed to (xxh3(key ‖ value), the export’s cursor/key column) so validate re-keys identically. None ⇒ un-keyed (a full export with no cursor). See ColumnChecksum.

Implementations§

Source§

impl RunManifest

Source

pub fn committed_rows(&self) -> i64

Sum of rows across Committed parts. Used by M5 sanity checks and by --reconcile to compare against source COUNT(*).

Source

pub fn committed_part_count(&self) -> usize

Number of Committed parts.

Source

pub fn validate_self_consistency(&self) -> Result<(), ManifestInconsistency>

Verify that the recorded aggregates (row_count, part_count) match the actual Committed parts in parts. A mismatch is a writer bug; callers should refuse to act on the manifest until investigated.
