Quick Start

import rhizo
from rhizo import QueryEngine
import pandas as pd

# Initialize storage
store = rhizo.PyChunkStore("./data/chunks")
catalog = rhizo.PyCatalog("./data/catalog")
engine = QueryEngine(store, catalog)

# Write data
df = pd.DataFrame({"id": [1, 2, 3], "name": ["Alice", "Bob", "Charlie"]})
engine.write_table("users", df)

# SQL queries with DuckDB
result = engine.query("SELECT * FROM users WHERE id > 1")
print(result.to_pandas())

# Time travel to any version
result_v1 = engine.query("SELECT * FROM users", versions={"users": 1})

Features

• SQL Queries: DuckDB-powered analytical queries
• Time Travel: Query any historical version
• Cross-Table ACID: Atomic transactions across multiple tables
• Git-like Branching: Zero-copy branches for experimentation
• Change Tracking: Subscribe to data changes
