`lumilake`

Python SDK for Lumilake server APIs and local deploy helpers. It provides sync and async resource clients for common server surfaces; the CLI remains the complete command surface for operational helpers. The SDK lives inside the lumilake distribution and ships behind the [sdk] extra so basic installs stay slim.

Install

Server-API + filesystem init (small surface; httpx only):

pip install 'lumilake[sdk]'

Add deploy lifecycle (client.deploy.up/down/...). Pulls in [deploy] (Docker SDK, FlowMesh stack helpers); client.deploy.* calls into lumilake_deploy directly:

pip install 'lumilake[sdk,deploy]'

In the workspace:

uv sync --group lint --group test --extra sdk --extra deploy

Without [deploy], every client.deploy.* method except init raises DeployError with an install hint on first call. Server-API resources work in either configuration.

Sync usage

from lumilake import LumilakeClient

with LumilakeClient.from_config() as client:        # reads ~/.lumilake/config.toml
    client.health()
    client.jobs.list()
    client.jobs.submit({"workflow": ...})
    client.deploy.up()

Async usage

from lumilake import AsyncLumilakeClient

async with AsyncLumilakeClient.from_config() as client:
    await client.health()
    await client.jobs.list()
    await client.jobs.submit({"workflow": ...})
    await client.deploy.up()

Constructing either client without .from_config() resolves the server URL in this order: explicit base_url=, LUMILAKE_BASE_URL, then ~/.lumilake/config.toml. .from_config(path=...) reads a specific TOML file directly.

CLI and SDK surfaces

Surface	Sync	Async
`lumilake deploy up`	writes `~/.lumilake/config.toml`	-
`lumilake info` / `health`	`client.health()`	same, await
`lumilake deploy {init,up,down,clean,restart,reset,logs,update-flowmesh}`	`client.deploy.<verb>(...)`	`await client.deploy.<verb>(...)`
`lumilake deploy {doctor,build,status}`	CLI only	CLI only
Job submit/preview/list/list_all/get/progress/result/inputs/artifact/cancel/wait/watch	`client.jobs.<verb>(...)`	`await client.jobs.<verb>(...)`
`lumilake worker {list,get}` (+ `list_all`)	`client.workers.<verb>(...)`	`await client.workers.<verb>(...)`
`lumilake trace {list,get}` (+ `list_all`)	`client.traces.<verb>(...)`	`await client.traces.<verb>(...)`

Design notes

Sync + async parity. One sync class, one async class, and each SDK resource exposes both. Shared base classes (BaseClient / BaseAsyncClient) handle version-prefix, envelope unwrapping, and error-to-exception mapping. Async resources await the same code paths.
Two transport modes. Server-API resources speak HTTP (httpx.Client / httpx.AsyncClient). Deploy lifecycle calls lumilake_deploy directly; async dispatches the same Python calls through asyncio.to_thread so the event loop stays responsive across Docker and FlowMesh setup work.
Config shared with the CLI. from_config() reads the same ~/.lumilake/config.toml the CLI writes from lumilake deploy up.
Never raw docker compose up. Deploy resource always uses the lumilake_deploy machinery — the project rule applies inside the SDK too.
Context-manager support. with LumilakeClient(...) as client: (sync) and async with AsyncLumilakeClient(...) as client: close the underlying httpx client cleanly.
