Install

The package is live on PyPI:

pip install tracedb

Install the aiohttp extra only when you want the optional aiohttp-backed async transport:

pip install "tracedb[aiohttp]"

Current generated-client usage:

from tracedb import TraceDB

client = TraceDB(
    base_url="http://127.0.0.1:8090",
    token="dev-token",
)

health = client.tracedb.health.get_health()
print(health)

The v0.1.1 package is the Fern-generated HTTP client. It exposes .tracedb resource clients and generated request/response models. This checkout does not expose wrapper helpers such as TraceDB.from_env(), table(...), insert_rows(...), fluent query builders, traceql(...), or graphql(...). Use the generated resource methods until a wrapper layer lands.

The package exposes __version__ = "0.1.1" and ships inline typing metadata for the generated client.

Claim Boundary

tracedb==0.1.1 is Python SDK packaging for the current TraceDB HTTP product surface. It does not claim managed-cloud readiness, hosted-alpha readiness, SQL compatibility, benchmark wins, production SLA, or wrapper-helper availability.

Installation

pip install tracedb

Reference

A full reference for this library is available here.

Usage

Instantiate and use the client with the following:

from tracedb import TraceDB

client = TraceDB(
    token="<token>",
)

client.tracedb.admin.post_admin_compact(
    request={
        "key": "value"
    },
)

Environments

This SDK allows you to configure different environments for API requests.

from tracedb import TraceDB
from tracedb.environment import TraceDBEnvironment

client = TraceDB(
    environment=TraceDBEnvironment.DEFAULT,
)

Async Client

The SDK also exports an async client so that you can make non-blocking calls to our API. Note that if you are constructing an Async httpx client class to pass into this client, use httpx.AsyncClient() instead of httpx.Client() (e.g. for the httpx_client parameter of this client).

import asyncio

from tracedb import AsyncTraceDB

client = AsyncTraceDB(
    token="<token>",
)


async def main() -> None:
    await client.tracedb.admin.post_admin_compact(
        request={
            "key": "value"
        },
    )


asyncio.run(main())

Exception Handling

When the API returns a non-success status code (4xx or 5xx response), a subclass of the following error will be thrown.

from tracedb.core.api_error import ApiError

try:
    client.tracedb.admin.post_admin_compact(...)
except ApiError as e:
    print(e.status_code)
    print(e.body)

Advanced

Access Raw Response Data

The SDK provides access to raw response data, including headers, through the .with_raw_response property. The .with_raw_response property returns a "raw" client that can be used to access the .headers and .data attributes.

from tracedb import TraceDB

client = TraceDB(...)
response = client.tracedb.admin.with_raw_response.post_admin_compact(...)
print(response.headers)  # access the response headers
print(response.status_code)  # access the response status code
print(response.data)  # access the underlying object

Retries

The SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long as the request is deemed retryable and the number of retry attempts has not grown larger than the configured retry limit (default: 2).

Which status codes are retried depends on the retryStatusCodes generator configuration:

legacy (current default): retries on

• 408 (Timeout)
• 409 (Conflict)
• 429 (Too Many Requests)
• 5XX (All server errors, including 500)

recommended: retries on

• 408 (Timeout)
• 409 (Conflict)
• 429 (Too Many Requests)
• 502 (Bad Gateway)
• 503 (Service Unavailable)
• 504 (Gateway Timeout)

Use the max_retries request option to configure this behavior.

client.tracedb.admin.post_admin_compact(..., request_options={
    "max_retries": 1
})

Timeouts

The SDK defaults to a 60 second timeout. You can configure this with a timeout option at the client or request level.

from tracedb import TraceDB

client = TraceDB(..., timeout=20.0)

# Override timeout for a specific method
client.tracedb.admin.post_admin_compact(..., request_options={
    "timeout_in_seconds": 1
})

Custom Client

You can override the httpx client to customize it for your use-case. Some common use-cases include support for proxies and transports.

import httpx
from tracedb import TraceDB

client = TraceDB(
    ...,
    httpx_client=httpx.Client(
        proxy="http://my.test.proxy.example.com",
        transport=httpx.HTTPTransport(local_address="0.0.0.0"),
    ),
)

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
