zippy-data 0.1.1

High-performance, multi-language dataset storage format

Zippy (ZDS) Python Package

High-performance, HuggingFace-compatible dataset storage format.

Installation

pip install zippy-zds

# With optional dependencies
pip install zippy-zds[pandas]
pip install zippy-zds[all]

Quick Start

from zippy import ZDSStore, ZDataset, ZIterableDataset

# Create a store
store = ZDSStore.open("./my_dataset", collection="train")

# Add documents
store.put("doc1", {"text": "Hello world", "label": 1})
store.put("doc2", {"text": "Goodbye world", "label": 0})

# Map-style dataset (random access)
dataset = store.to_dataset()
print(dataset[0])  # {"text": "Hello world", "label": 1}
print(len(dataset))  # 2

# Iterable dataset (streaming)
iterable = store.to_iterable_dataset()
for doc in iterable:
    print(doc)

# With shuffle buffer
for doc in iterable.shuffle(buffer_size=1000):
    print(doc)

DataFrame Integration

from zippy import read_zds, to_zds

# Load as DataFrame (requires pandas)
df = read_zds("./my_dataset", collection="train")

# Export DataFrame to ZDS
to_zds(df, "./output", collection="exported")

HuggingFace Compatibility

ZDS datasets are designed to work seamlessly with HuggingFace training loops:

from zippy import ZIterableDataset

dataset = ZIterableDataset.from_store("./my_dataset", collection="train")

# Works with DataLoader
from torch.utils.data import DataLoader
loader = DataLoader(dataset, batch_size=32)
