# Run Config

The `run_config` module defines runtime settings that control dataset generation behavior,
including early shutdown thresholds, batch sizing, and non-inference worker concurrency.

## Usage

```python
import data_designer.config as dd
from data_designer.interface import DataDesigner

data_designer = DataDesigner()
data_designer.set_run_config(dd.RunConfig(
    buffer_size=500,
    max_conversation_restarts=3,
))
```

feat: Elevate non-LLM concurrency limits to `RunConfig` (#242) 2026-01-26 16:11:36 +00:00			`# Run Config`

			The `run_config` module defines runtime settings that control dataset generation behavior,
			`including early shutdown thresholds, batch sizing, and non-inference worker concurrency.`

feat: add message trace support for LLM generation (#272) Add support for capturing full conversation traces during LLM generation, enabling debugging and fine-tuning dataset creation. Changes: - Add `with_trace` field to LLMTextColumnConfig for per-column trace control - Add `debug_override_save_all_column_traces` to RunConfig for global trace - Introduce ChatMessage dataclass for structured message representation - Update ModelFacade.generate() to return full message trace - Rename trace column postfix from `__reasoning_trace` to `__trace` - Add comprehensive traces documentation Traces capture system/user/assistant messages in order, enabling visibility into the full generation conversation including correction retries. 2026-01-30 22:03:07 +00:00			`## Usage`
