§manifest_length: i64

field: 501

Length of the manifest file in bytes

§partition_spec_id: i32

field: 502

ID of a partition spec used to write the manifest; must be listed in table metadata partition-specs

§content: ManifestContentType

field: 517

The type of files tracked by the manifest, either data or delete files; 0 for all v1 manifests

§sequence_number: i64

field: 515

The sequence number when the manifest was added to the table; use 0 when reading v1 manifest lists

§min_sequence_number: i64

field: 516

The minimum data sequence number of all live data or delete files in the manifest; use 0 when reading v1 manifest lists

§added_snapshot_id: i64

field: 503

ID of the snapshot where the manifest file was added

§added_files_count: Option<u32>

field: 504

Number of entries in the manifest that have status ADDED, when null this is assumed to be non-zero

§existing_files_count: Option<u32>

field: 505

Number of entries in the manifest that have status EXISTING (0), when null this is assumed to be non-zero

§deleted_files_count: Option<u32>
