• branch_name Optional[str] - Read/write branch for Lance operations. Uses main if not set.
• embeddings Union[LanceEmbeddingsConfiguration, Dict[str, Any]], optional - Embedding provider, model, and credentials. If not provided, no vector column is added.
• destination_name str, optional - Name of the destination.
• environment str, optional - Environment of the destination.
