Fluxum Python SDK

The asyncio-first Python client for the Fluxum realtime database (SPEC-011, T7.4). Zero runtime dependencies — the SDK carries its own minimal MessagePack codec and FluxBIN row reader.

pip install fluxum-sdk

import asyncio
from fluxum import Connection, TableSchema

async def main():
    db = await Connection.connect(
        "fluxum://127.0.0.1:15801",
        token=b"my-token",
        tables=[...],  # from `fluxum generate --lang python`
    )
    await db.subscribe(["SELECT * FROM ChatMessage"])
    await db.call_reducer("send_chat", [1, "hello"])
    # TxUpdates land in db.cache; poll or read db.cache.rows("ChatMessage").
    await db.close()

asyncio.run(main())

What you get

  • Connection — one asyncio session over FluxRPC/TCP: authenticate, subscribe (each query's InitialData populates a local row cache), call reducers, and receive TxUpdate diffs on the same socket.
  • Transparent reconnect (SDK-047): on connection loss the client reconnects, re-authenticates, resubscribes every active query and reconciles its cache — the application keeps its handle across the outage.
  • A per-table row cache keyed by primary key, with per-query ownership so an unsubscribe drops only the rows that query held (SDK-044).
  • Full type hints (py.typed, SDK-062).

Typed bindings

Generate typed row classes and reducer wrappers from a running server's schema (or a saved schema.json):

fluxum generate --lang python --schema http://127.0.0.1:15800 --out ./gen

This emits tables.py (a @dataclass row + decoder + cache hooks per table), reducers.py (a typed async def per client-callable reducer), __init__.py, and py.typed. Offline generation from a saved schema produces byte-identical output (SPEC-011 acceptance 11).

Testing

The SDK is validated by the shared conformance corpus (tests/conformance/) — the same declarative scenarios every Fluxum SDK runs against the same server build (TST-052). The runner boots a fresh fluxum-server per scenario, so build it first:

cargo build -p fluxum-server
cd sdks/python && python -m pytest -q
