Output fields that uniquely identify each document within a source object. Enables idempotent reprocessing: rerunning a batch produces the same document IDs, so existing documents are updated instead of creating duplicates. Works with bucket unique_key to enable fully deterministic document IDs. Empty list means single-output extractor (one document per source). Read-only (set by extractor).

Examples:
["start_time", "end_time"]
["chunk_index"]
