Description

I'd like to use architecture arm64 instead of the default x86_64 for my data function resolvers.

It would be great to use something like this:

export const myFunction = defineFunction({ runtime: 20, architecture: 'arm64' });

Hey @otottkovacstibor, 👋 thanks for raising this! Marking this as feature request for further evaluation.

[ykethan]

note: you can set the architecture of the function by overriding the value

backend.myApiFunction.resources.cfnResources.cfnFunction.architectures = [
  "arm64",
];

I have created a new PR compatible with the most up-to-date amplify-backend version: #2370

@otottkovacstibor It was merged onto main branch! :) So now we just have to wait for the next release.
