| [`FileGroupTask`](#nemo_curator-tasks-file_group-FileGroupTask) | Task representing a group of files to be read. |

### API

```python
class nemo_curator.tasks.FileGroupTask(
    dataset_name: str,
    data: list[str] = list(),
    _stage_perf: list[nemo_curator.utils.performance_utils.StagePerfStats] = list(),
    _metadata: dict[str, typing.Any] = dict(),
    reader_config: dict[str, typing.Any] = dict()
)
```

Dataclass

**Bases:** [Task\[list\[str\]\]](/nemo/curator/nemo-curator/nemo_curator/tasks/tasks#nemo_curator-tasks-tasks-Task)

Task representing a group of files to be read.
This is created during the planning phase and passed to reader stages.

**`data`** `list[str] = field(default_factory=list)`

---

**`num_items`** `int`

Number of files in this group.

---

**`reader_config`** `dict[str, Any] = field(default_factory=dict)`

---

```python
nemo_curator.tasks.FileGroupTask.get_deterministic_id() -> str
```

Content-based id derived from the sorted file paths. Stable
across runs even if the source stage emits the file group at a
different position (e.g. because new files were added or removed
between runs).

```python
nemo_curator.tasks.FileGroupTask.validate() -> bool
```

Validate the task data.
