Getting Started¶
Installation¶
Usage¶
from capo_migrationhub_config import AsyncMigrationHubConfigClient
async def main():
async with AsyncMigrationHubConfigClient() as migration_hub_config:
# Example: call the create_home_region_control operation
response = await migration_hub_config.create_home_region_control()
print(response["home_region_control"])
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_migrationhub_config import AsyncMigrationHubConfigClient
async def main():
async with AsyncMigrationHubConfigClient() as migration_hub_config:
# Example: paginate over describe_home_region_controls
async for item in migration_hub_config.iter_describe_home_region_controls():
print(item)
Error Handling¶
The SDK raises exceptions for errors returned by the API. Catch them to handle failures gracefully.
from capo_migrationhub_config import AsyncMigrationHubConfigClient
from capo_migrationhub_config.error import AccessDeniedException
async def main():
async with AsyncMigrationHubConfigClient() as migration_hub_config:
try:
await migration_hub_config.create_home_region_control()
except AccessDeniedException 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_migrationhub_config import AsyncMigrationHubConfigClient
async def main():
async with AsyncMigrationHubConfigClient() as migration_hub_config:
# Default: 3 attempts for every operation
response = await migration_hub_config.create_home_region_control()
# Override per operation
response = await migration_hub_config.create_home_region_control(config_overrides={"retry_max_attempts": 5})
# Disable retries for this call
response = await migration_hub_config.create_home_region_control(config_overrides={"retry_max_attempts": 1})
