Async boto3 wrapper

Project description

Async AWS SDK for Python Documentation Status Updates

aiobotocore has been copied into this project, and updated until is merged

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 use 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


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(


loop = asyncio.get_event_loop()

# 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


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


Docs are here -

Examples here -


  • Closely mimics the usage of boto3.


  • More Examples
  • Set up docs
  • Look into monkey-patching the aws xray sdk to be more async if it needs to be.


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.


5.0.0 (2018-10-12)

  • Updated lots of dependencies
  • Changed s3.upload_fileobj from using put_object to doing a multipart upload
  • Created s3.copy shim that runs get_object then does multipart upload, could do with a better implementation though.

4.1.2 (2018-08-28)

  • updated pypi credentials

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.

3.0.0 (2018-03-29)

  • Dependancy bump
  • Asyncified dynamodb Table Batch Writer + Tests
