 You can use this information to pull only the partition you're interested in, eg
 
 ```python
-from huggingface_hub import hf_hub_download
+from pathlib import Path
+from huggingface_hub import snapshot_download
+import pyarrow.dataset as ds
 
-# Download a single partition file and store it in the local cache
-local_file = hf_hub_download(
-    repo_id="BrentLab/harbison_2004",
+# pull all data for regulator `YAL051W`
+root = snapshot_download(
+    repo_id="BrentLab/hackett_2020",

+    allow_patterns=[

+base = Path(root) / "data"  # the dataset root directory
+dataset = ds.dataset(base, format="parquet", partitioning="hive")
