aioboto3 4.1.2

Async boto3 wrapper

Async AWS SDK for Python

This package is mostly just a wrapper combining the great work of boto3 and aiobotocore.

aiobotocore allows you to use near enough all of the boto3 client commands in an async manner just by prefixing the command with await.

With aioboto3 you can now usxe the higher level APIs provided by boto3 in an asynchronous manner. Mainly I developed this as I wanted to use the boto3 dynamodb Table object in some async microservices.

While all resources in boto3 should work I havent tested them all, so if what your after is not in the table below then try it out, if it works drop me an issue with a simple test case and I’ll add it to the table.

Services	Status
DynamoDB Service Resource	Tested and working
DynamoDB Table	Tested and working
S3	Working
Kinesis	Working
SSM Parameter Store	Working
Athena	Working

Example

Simple example of using aioboto3 to put items into a dynamodb table

import asyncio
import aioboto3
from boto3.dynamodb.conditions import Key


async def main():
    async with aioboto3.resource('dynamodb', region_name='eu-central-1') as dynamo_resource:
        table = dynamo_resource.Table('test_table')

        await table.put_item(
            Item={'pk': 'test1', 'col1': 'some_data'}
        )

        result = await table.query(
            KeyConditionExpression=Key('pk').eq('test1')
        )

        print(result['Items'])

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

# Outputs:
#  [{'col1': 'some_data', 'pk': 'test1'}]

Things that either dont work or have been patched

As this library literally wraps boto3, its inevitable that some things won’t magically be async.

• s3_client.copy This is performed by the s3transfer module. I believe s3_client.copy_object performs the same function

Fixed:

• s3_client.download_file* This is performed by the s3transfer module. – Patched with get_object

• s3_client.upload_file* This is performed by the s3transfer module. – Patched with put_object

• dynamodb_resource.Table.batch_writer This now returns an async context manager which performs the same function

Features

• Closely mimics the usage of boto3.

Todo

• More Examples

• Set up docs

• Look into monkey-patching the aws xray sdk to be more async if it needs to be.

Credits

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template. It also makes use of the aiobotocore and boto3 libraries. All the credit goes to them, this is mainly a wrapper with some examples.

History

4.1.0 (2018-08-28)

• aiobotocore dependancy bump

4.0.2 (2018-08-03)

• Dependancy bump

4.0.0 (2018-05-09)

• Dependancy bump

• Now using aiobotocore 0.8.0

• Dropped < py3.5 support

• Now using async def / await syntax

• Fixed boto3 dependancy so it only uses a boto3 version supported by aiobotocore’s max botocore dependancy

• Important, `__call__` in `AIOServiceAction` tries to yield from a coroutine in a non-coroutine, this code shouldn’t be hit anymore but I can’t guarantee that, so instead `__call__` was duplicated and awaited properly so “should” be fine. Credit goes to Arnulfo Solis for doing PR.
