capo-iotsitewise: typed, async Python SDK for AWS Iotsitewise¶

capo-iotsitewise is a typed Python SDK for AWS Iotsitewise. It has an async client, AsyncIoTSiteWiseClient, for asyncio and trio, and a sync client, IoTSiteWiseClient, with the same methods. Requests and responses are typed with TypedDicts, so your editor and type checker know every field.

It is part of capo, a community-driven alternative to boto3 and aioboto3, built on its own HTTP stack instead of botocore and generated from the official AWS Smithy models. Documentation: https://capo-sdk.dev/services/iotsitewise/

Installation¶

pip install capo-iotsitewise

Usage¶

from capo_iotsitewise import AsyncIoTSiteWiseClient


async def main():
    async with AsyncIoTSiteWiseClient() as io_t_site_wise:
        # Example: call the associate_assets operation
        response = await io_t_site_wise.associate_assets()
        print(response)

Pagination¶

Some operations in this SDK support pagination. If the operation supports pagination it will have an iter_ prefixed method that returns an async iterator.

from capo_iotsitewise import AsyncIoTSiteWiseClient


async def main():
    async with AsyncIoTSiteWiseClient() as io_t_site_wise:
        # Example: paginate over batch_get_asset_property_aggregates
        async for item in io_t_site_wise.iter_batch_get_asset_property_aggregates():
            print(item)

Waiters¶

Waiters poll an operation until a resource reaches a desired state. If the operation supports waiters it will have a wait_until_ prefixed method.

from capo_iotsitewise import AsyncIoTSiteWiseClient


async def main():
    async with AsyncIoTSiteWiseClient() as io_t_site_wise:
        # Example: wait for asset_not_exists
        await io_t_site_wise.wait_until_asset_not_exists(max_wait_time=300)

Error Handling¶

The SDK raises exceptions for errors returned by the API. Catch them to handle failures gracefully.

from capo_iotsitewise import AsyncIoTSiteWiseClient
from capo_iotsitewise.error import ConflictingOperationException


async def main():
    async with AsyncIoTSiteWiseClient() as io_t_site_wise:
        try:
            await io_t_site_wise.associate_assets()
        except ConflictingOperationException as e:
            print(f"Error: {e}")
            print(e.data)  # additional error data

Retrying¶

The SDK retries failed operations automatically. Retry behaviour follows the Smithy specification: errors are retried based on their is_retryable and is_throttling_error attributes. Throttling errors use a longer base delay. Network-level failures (connection errors and timeouts) are also retried. Non-retryable errors, such as client errors without the @retryable trait, are raised immediately without further attempts.

The number of attempts defaults to 3 and can be changed at the client level via retry_max_attempts, or per call via config_overrides.

from capo_iotsitewise import AsyncIoTSiteWiseClient


async def main():
    async with AsyncIoTSiteWiseClient() as io_t_site_wise:
        # Default: 3 attempts for every operation
        response = await io_t_site_wise.associate_assets()

        # Override per operation
        response = await io_t_site_wise.associate_assets(config_overrides={"retry_max_attempts": 5})

        # Disable retries for this call
        response = await io_t_site_wise.associate_assets(config_overrides={"retry_max_attempts": 1})
