Async client for amazon services using botocore and aiohttp/asyncio_.
This library is a mostly full featured asynchronous version of botocore.
::
$ pip install aiobotocore
.. code:: python
import asyncio
from aiobotocore.session import get_session
AWS_ACCESS_KEY_ID = "xxx"
AWS_SECRET_ACCESS_KEY = "xxx"
async def go():
bucket = 'dataintake'
filename = 'dummy.bin'
folder = 'aiobotocore'
key = '{}/{}'.format(folder, filename)
session = get_session()
async with session.create_client('s3', region_name='us-west-2',
aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
aws_access_key_id=AWS_ACCESS_KEY_ID) as client:
# upload object to amazon s3
data = b'\x01'*1024
resp = await client.put_object(Bucket=bucket,
Key=key,
Body=data)
print(resp)
# getting s3 object properties of file we just uploaded
resp = await client.get_object_acl(Bucket=bucket, Key=key)
print(resp)
# get object from s3
response = await client.get_object(Bucket=bucket, Key=key)
# this will ensure the connection is correctly re-used/closed
async with response['Body'] as stream:
assert await stream.read() == data
# list s3 objects using paginator
paginator = client.get_paginator('list_objects')
async for result in paginator.paginate(Bucket=bucket, Prefix=folder):
for c in result.get('Contents', []):
print(c)
# delete object from s3
resp = await client.delete_object(Bucket=bucket, Key=key)
print(resp)
loop = asyncio.get_event_loop()
loop.run_until_complete(go())
.. code:: python
from contextlib import AsyncExitStack
from aiobotocore.session import AioSession
# How to use in existing context manager
class Manager:
def __init__(self):
self._exit_stack = AsyncExitStack()
self._s3_client = None
async def __aenter__(self):
session = AioSession()
self._s3_client = await self._exit_stack.enter_async_context(session.create_client('s3'))
async def __aexit__(self, exc_type, exc_val, exc_tb):
await self._exit_stack.__aexit__(exc_type, exc_val, exc_tb)
# How to use with an external exit_stack
async def create_s3_client(session: AioSession, exit_stack: AsyncExitStack):
# Create client and add cleanup
client = await exit_stack.enter_async_context(session.create_client('s3'))
return client
async def non_manager_example():
session = AioSession()
async with AsyncExitStack() as exit_stack:
s3_client = await create_s3_client(session, exit_stack)
# do work with s3_client
This is a non-exuastive list of what tests aiobotocore runs against AWS services. Not all methods are tested but we aim to test the majority of commonly used methods.
+----------------+-----------------------+ | Service | Status | +================+=======================+ | S3 | Working | +----------------+-----------------------+ | DynamoDB | Basic methods tested | +----------------+-----------------------+ | SNS | Basic methods tested | +----------------+-----------------------+ | SQS | Basic methods tested | +----------------+-----------------------+ | CloudFormation | Stack creation tested | +----------------+-----------------------+ | Kinesis | Basic methods tested | +----------------+-----------------------+
Due to the way boto3 is implemented, its highly likely that even if services are not listed above that you can take any boto3.client('service')
and
stick await
infront of methods to make them async, e.g. await client.list_named_queries()
would asynchronous list all of the named Athena queries.
If a service is not listed here and you could do with some tests or examples feel free to raise an issue.
There are two set of tests, those that can be mocked through moto <https://github.com/getmoto/moto>
_ running in docker, and those that require running against a personal amazon key. The CI only runs the moto tests.
To run the moto tests:
::
$ make mototest
To run the non-moto tests:
Make sure you have development requirements installed and your amazon key and secret accessible via environment variables:
::
$ pip install pip-tools
$ pip-compile requirements-dev.in
$ pip-sync requirements-dev.txt
$ export AWS_ACCESS_KEY_ID=xxx
$ export AWS_SECRET_ACCESS_KEY=xxx
$ export AWS_DEFAULT_REGION=xxx # e.g. us-west-2
Execute tests suite:
::
$ make test
Install types-aiobotocore that contains type annotations for aiobotocore
and all supported botocore services.
.. code:: bash
# install aiobotocore type annotations
# for ec2, s3, rds, lambda, sqs, dynamo and cloudformation
python -m pip install 'types-aiobotocore[essential]'
# or install annotations for services you use
python -m pip install 'types-aiobotocore[acm,apigateway]'
# Lite version does not provide session.create_client overloads
# it is more RAM-friendly, but requires explicit type annotations
python -m pip install 'types-aiobotocore-lite[essential]'
Now you should be able to run Pylance, pyright, or mypy_ for type checking as well as code completion in your IDE.
For types-aiobotocore-lite
package use explicit type annotations:
.. code:: python
from aiobotocore.session import get_session
from types_aiobotocore_s3.client import S3Client
session = get_session()
async with session.create_client("s3") as client:
client: S3Client
# type checking and code completion is now enabled for client

awscli and boto3 depend on a single version, or a narrow range of versions, of botocore. However, aiobotocore only supports a specific range of botocore versions. To ensure you install the latest version of awscli and boto3 that your specific combination or aiobotocore and botocore can support use::
pip install -U 'aiobotocore[awscli,boto3]'
If you only need awscli and not boto3 (or vice versa) you can just install one extra or the other.
