aioboto3 incompatible with AWS Python 3.12 runtime

[cderossi]

The AWS Lambda Python 3.12 runtime currently provides boto3 and botocore version 1.38.36.

Only aiobotocore 2.23.1 is compatible with this version of botocore, specifically:

dependencies = [
    "aiohttp >= 3.9.2, < 4.0.0",
    "aioitertools >= 0.5.1, < 1.0.0",
    "botocore >= 1.38.31, < 1.38.37",

There is no version of aioboto3 which is compatible with aiobotocore 2.23.1. There is one for 2.23.0.

If you pip install boto3==1.38.26 botocore==1.38.26 aioboto3, you get version 2.23.1 of aiobotocore and version 1.0.0 of aioboto3.

aiobotocore 2.23.1 (https://github.com/aio-libs/aiobotocore/blob/2.23.1/pyproject.toml) has this "boto3 >= 1.38.40, < 1.38.47", constraint so there isn't an aiobotocore version that fits that constraint either.

2.23.0 has a lower constraint. So there is not much I can do here.

Right you are. Sorry; I was looking at the wrong commit in that version.

FWIW, both of the runtimes that AWS provides for 3.12 and 3.13 as of today use boto3/botocore 1.38.36. But, like you say, not something you can address here.

@idiodoneo-chris is there anything stopping you bundling you're own boto3/botocore in a lambda archive? I've not tested it so not sure what one would get loaded
