BriskDB for Python

This package runs BriskDB's sharded SQLite engine in the Python process. It starts no listener, subprocess, signal handler, or global logger.

Tagged releases publish compiler-free wheels for CPython 3.9–3.14 on supported macOS and Linux targets:

python -m pip install --only-binary=:all: briskdb

To build the current checkout from source, use Python 3.9+ and Rust 1.85+:

python -m pip install ./python

import briskdb

db = briskdb.open("./data", shards=4)
session = db.session(routing_key="account-1")
session.migrate("CREATE TABLE notes (id INTEGER PRIMARY KEY, body TEXT NOT NULL)")
session.execute("INSERT INTO notes VALUES (?1, ?2)", [1, "hello"])
print(session.query("SELECT body FROM notes WHERE id = ?1", [1]))
session.close()
db.close()

Resource limits can be validated before the database opens:

config = briskdb.Config(shards=4, max_result_rows=5_000)
db = briskdb.open("./data", config=config)

Database and session handles own their native resources, close() is idempotent, and blocking engine work releases Python's GIL. Dropping live handles during interpreter shutdown is also safe.

Synchronous handles support with; the asyncio facade keeps engine work off the event loop and propagates task cancellation into Rust:

async with await briskdb.open_async("./data", shards=4) as db:
    async with await db.session(routing_key="account-1") as session:
        rows = await session.query("SELECT body FROM notes WHERE id = ?1", [1])

See sync and asyncio usage for cursors, deadlines, cancellation, thread/task safety, and the intentionally unclaimed DB-API transaction surface. The API reference, platform matrix, and serverless-shaped warm-handler example define the supported package surface and its current boundaries.

This is an alpha API. SQL supports None, bool, bounded integers, float, str, bytes-like values, and exact decimal.Decimal conversion with explicit errors when SQLite cannot store a value losslessly. See the executable value and exception contract for boundaries and the stable BriskDBError hierarchy.

Native Mongo/document commands are not claimed until BriskDB's document engine lands. The extension uses only the listener-free embedded Rust feature.
