Struct LoadedRowLineage 

pub struct LoadedRowLineage {
    pub row_ids: Option<Arc<RowIdSequence>>,
    pub created_at: Option<Arc<RowDatasetVersionSequence>>,
    pub last_updated_at: Option<Arc<RowDatasetVersionSequence>>,
}

One fragment’s row lineage sequences that live outside the manifest, read ahead of a commit by the caller.

Building a manifest is synchronous and has no object store, so it cannot read a sequence spilled to a data file column (RowIdMeta::Column, RowDatasetVersionMeta::Column). A caller that can do IO loads them first and hands them over in ManifestBuildConfig. Only the spilled sequences need to be present; inline ones are decoded on the spot.

Fields

row_ids: Option<Arc<RowIdSequence>>

created_at: Option<Arc<RowDatasetVersionSequence>>

last_updated_at: Option<Arc<RowDatasetVersionSequence>>
