# osu-everything

`osu-everything` contains the source tools and runbooks for maintaining the
compact v1 osu! dataset in:

```text
hf://buckets/lekdan/osu-everything
```

The source checkout is a normal Git repo. Runtime dataset state lives outside
the checkout in a sibling dataset workspace.

```text
~/osu_model/          # source checkout: code, docs, schemas, feature pipeline
~/osu_model_dataset/  # working dataset state: archives, data, fetcher DB, logs
~/osu_model_features/ # derived feature store output
```

The scripts default to that sibling layout. Override it with
`DATASET_ROOT=/path/to/workspace` when needed.

## Bucket Layout

```text
osu-everything/
├── archives/sha256/aa/bb/<archive_sha256>.osz
├── data/v1/
│   ├── all_revisions/<table>/part-<batch>.parquet
│   └── latest/<table>/part-*.parquet
├── schemas/v1/*.schema.json
├── features/v1/
│   ├── schemas/
│   │   ├── features_v1.schema.json
│   │   ├── feature_tables/*.schema.json
│   │   └── state_tables/*.schema.json
│   ├── docs/
│   ├── state/
│   ├── tables/
│   └── audio/
└── state/fetcher/state.db
```

The bucket stores raw `.osz` archives and compact Parquet metadata. It does
not publish extracted blobs, manifests, train/test splits, or a global blob
registry.

`schemas/v1/` is only for the compact dataset contract. Derived feature
schemas live under `features/v1/schemas/`; do not create
`schemas/v1/features.json` or put feature table schemas beside the compact
dataset schemas.

`all_revisions` is the append-only metadata history. `latest` is regenerated
from that history for quick reads and ML workloads.

`features/v1/` is the derived ML feature store. Its schema and docs are stored
inside the feature subtree so a bucket sync of `features/v1` carries both the
Parquet files and the feature data contract.

## Loading Data

Sync only the prefix you need:

```bash
hf sync \
  hf://buckets/lekdan/osu-everything/data/v1/latest/beatmaps \
  ./osu-everything/data/v1/latest/beatmaps
```

Load with PyArrow:

```python
import pyarrow.dataset as ds

beatmaps = ds.dataset(
    "./osu-everything/data/v1/latest/beatmaps",
    format="parquet",
).to_table()
```

Raw audio, images, videos, and `.osu` text remain inside the original `.osz`
archives under `archives/`. Metadata rows carry archive paths and member paths
needed to locate those bytes.

Derived feature rows can be loaded the same way:

```python
import pyarrow.dataset as ds

objects = ds.dataset(
    "./osu-everything/features/v1/tables/object_tokens_osu",
    format="parquet",
).to_table()
```

## Updating

Clone or update source with Git:

```bash
git clone https://huggingface.co/datasets/lekdan/osu-everything-tools ~/osu_model
cd ~/osu_model
git pull --ff-only
```

Build the tools:

```bash
uv sync
cargo build --release -p osu_indexer -p osu_fetcher
```

Configure local osu! credentials in the dataset workspace:

```bash
mkdir -p ~/osu_model_dataset
cp osu_fetcher.toml.example ~/osu_model_dataset/osu_fetcher.toml
# fill in ~/osu_model_dataset/osu_fetcher.toml
```

Run a normal update:

```bash
UPLOAD=1 DOWNLOAD_CONCURRENCY=128 bash scripts/update_maps_v1.sh
```

The wrapper hydrates only bucket `data/`, `schemas/`, and `state/fetcher/`,
fetches new or changed `.osz` files, ingests them, compacts metadata by
default, regenerates latest views, and publishes the changed dataset prefixes.
It does not download the historical archive corpus.

See `docs/PIPELINE_RUNBOOK.md` for operational details.

Derived ML features are built separately after compact metadata has been
updated. See `osu_feature_pipeline/README.md`.

## Source Changes

Make code and documentation changes in `~/osu_model`, then use normal Git:

```bash
git status --short
git add README.md docs scripts python crates schemas osu_feature_pipeline Cargo.toml Cargo.lock pyproject.toml uv.lock
git commit -m "describe the source change"
git push
```

Do not put runtime dataset state in the source commit. The source repo ignores
`archives/`, `data/`, `.fetcher/`, `.scratch/`, `incoming_osz/`, `logs/`,
`target/`, `.venv/`, and local credential files.

## Licensing

Beatmaps frequently include copyrighted songs, backgrounds, videos, and
storyboard assets. Do not publish this dataset publicly without the
appropriate rights. Refer to the osu! beatmap licence before sharing.
