Getting Started

Installation

pip install capo-application-auto-scaling

Usage

from capo_application_auto_scaling import AsyncApplicationAutoScalingClient


async def main():
    async with AsyncApplicationAutoScalingClient() as application_auto_scaling:
        # Example: call the delete_scaling_policy operation
        response = await application_auto_scaling.delete_scaling_policy()
        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_application_auto_scaling import AsyncApplicationAutoScalingClient


async def main():
    async with AsyncApplicationAutoScalingClient() as application_auto_scaling:
        # Example: paginate over describe_scalable_targets
        async for item in application_auto_scaling.iter_describe_scalable_targets():
            print(item)

Error Handling

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

from capo_application_auto_scaling import AsyncApplicationAutoScalingClient
from capo_application_auto_scaling.error import ConcurrentUpdateException


async def main():
    async with AsyncApplicationAutoScalingClient() as application_auto_scaling:
        try:
            await application_auto_scaling.delete_scaling_policy()
        except ConcurrentUpdateException 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_application_auto_scaling import AsyncApplicationAutoScalingClient


async def main():
    async with AsyncApplicationAutoScalingClient() as application_auto_scaling:
        # Default: 3 attempts for every operation
        response = await application_auto_scaling.delete_scaling_policy()

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

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