Behavior when SQL query returns no rows. Values: SKIP: Keep document unchanged, do not set output_field - Document passes through without enrichment - Best for optional lookups NULL: Set output_field to null - Explicitly marks no result found - Useful for downstream conditional logic ERROR: Raise error and fail enrichment - Strict mode for mandatory data - Use with on_error to control pipeline behavior
