Get Parent Lineage for a Table — datom_get

Reads the parents field from a table's metadata. Returns the lineage entries recorded at write time by dp_dev or other callers. For imported tables or derived tables with no recorded lineage, returns NULL.

Arguments

conn: A datom_conn object from datom_get_conn().
name: Table name.
version: Optional metadata_sha (datom version). If NULL, reads current metadata. If provided, fetches the versioned metadata snapshot from S3.

Value

List of parent entries (each with source, table, version), or NULL if no lineage is recorded.
