Add support for Python 3.11

[michael-k]

Latest official update [2023-01-09]:

We are currently working on Py3.10 support (see #31). Py3.11 will ship separately. We don't currently have a timeline to share on Py3.11 support. We will we post updates on this issue when we have further information to share.

And another official update from a different thread [2023-02-28]:

We don't have a ETA to share as yet.

(I know that 3.10 isn't available yet on Lambda; but AWS could add both at the same time and not let us wait for > 1 year until they add 3.11 🙏)

Thank you for creating this ticket. We are currently working on Python 3.10 support, with Python 3.11 to follow later. We are also working to improve our runtime release process to enable us to release new runtimes more quickly.

Any timeframe on this? 3.11 is critical for us.

They still don't have Python 3.10 ready and it's been over a year since its release. You might be waiting a LONG time

Maybe start with an alpha version like 3.12.0a2 then it would take less time to add a new stable version when it releases.

@fox91 @jorwoods why thumbs down? It is a standard approach to prepare with early builds before final release to speed up the adaption process and catch all the issues earlier. AWS can do this too.

Open another issue, this is for 3.11 only. What does 3.12 have to do with it here?

It's possible to run 3.11 with a custom runtime, for example:
https://github.com/hb2638/aws_lambda_python_3.11
https://github.com/keithly/lambda-python-custom

[CharlesPerrotMinotHCHB]

True, but a custom runtime isn't an official one, hence will always present a security threat potential. Unless you import it, redo it yourself, and many companies won't really consider it worth the work compared to the gains of the update.

To clarify, I believe @baotran2207 's comment above reflects a desire for when s/he would like AWS Lambda to support Python 3.11. It is not a statement from AWS on when Python 3.11 will be supported.

We are currently working on Py3.10 support (see #31). Py3.11 will ship separately. We don't currently have a timeline to share on Py3.11 support. We will we post updates on this issue when we have further information to share.

Given that 3.11 is so much faster (10–60%), I'm curious what would be the take of aws managment on prioritizing this runtime, considering that the faster execution time will directly translate into smaller lambda bills.

Of course, the rational thing to do as customers here is to re-calculate the cost of alternative compute systems and perhaps use lambda less.

now you have the answer :) they need larger bills, not smaller. So for 3.11 they need to port all the slowdowns back 🤭

Amazon Linux 2023 is now GA, and contains Python 3.11 packages as an option (system python in AL2023 will remain as 3.9, but 3.11 is fully functional with pip)
