turbine-client

Typed HTTP client for the Turbine management API. Sync and async siblings; both speak the /api/v1/manage/... surface and accept any httpx.Auth strategy.

Use this when you want to call a running Turbine server from your own code — outside of a dagster-turbine or airflow-turbine integration.

Install

uv add turbine-client

Python 3.12 or newer.

Minimal example

from turbine_client import TurbineClient

client = TurbineClient("http://turbine:8000")
contracts = client.list_contracts()           # list every registered contract
sessions = client.start_runs(["orders"])      # fan out one Check Run per contract id
result = sessions[0].wait()                   # block until the run is terminal
print(result.status, [r.outcome for r in result.results])

Contract selection

start_runs accepts three shapes:

• start_runs("orders") — single contract, one run.
• start_runs(["orders", "customers"]) — explicit list, one run per id.
• start_runs(None) (the default) — fan out across every registered contract.

start_run(contract_id) is the atomic primitive — one contract, one run handle.

Check Window and run options

start_runs (and start_run) accept four optional kwargs:

Auth

Pass any httpx.Auth subclass via the auth= kwarg. Two helpers ship with the package:

from turbine_client import TurbineClient, BearerAuth, AzureADClientCredentials

client = TurbineClient("http://turbine:8000", auth=BearerAuth(token="..."))

# OAuth client-credentials (e.g. behind the PAX ingress gateway):
client = TurbineClient(
    "https://turbine.example.com",
    auth=AzureADClientCredentials(
        tenant_id="...", client_id="...", client_secret="...",
        scope="api://turbine/.default",
    ),
)

Leave auth=None for in-cluster, unauthenticated deployments.

Async client

AsyncTurbineClient mirrors TurbineClient; every network method returns a coroutine. Use it from any asyncio event loop — including the Airflow triggerer process.

from turbine_client import AsyncTurbineClient

async def main() -> None:
    client = AsyncTurbineClient("http://turbine:8000")
    sessions = await client.start_runs(["orders"])
    result = await sessions[0].wait()

Compatibility

turbine-client >= 0.5.12 requires turbine-data >= 0.5.12 on the server (Contract Selection + Check Severity round-trip require both the POST /checks/runs endpoint and the severity field on the registry response). The client carries no runtime version negotiation; older clients keep working against newer servers because API additions are additive on /api/v1.
