#20831 faas pex should allow users to change default platform Issue created by ravi2024sk Can we change default platform when we generate google cloud function python zip file? here it is hardcoded to manylinux2014:

@rule
async def build_python_faas(
    request: BuildPythonFaaSRequest,
) -> BuiltPackage:
    additional_pex_args = (
        # Ensure we can resolve manylinux wheels in addition to any AMI-specific wheels.
        "--manylinux=manylinux2014",
        # When we're executing Pex on Linux, allow a local interpreter to be resolved if
        # available and matching the AMI platform.
        "--resolve-local-platforms",
    )

Looks like certain python libraries no longer release a linux version for manylinux2014. For example pyarrow:

| stderr:

build-1  | A distribution for pyarrow could not be resolved for cp312-cp312-linux_x86_64.

build-1  | Found 1 distribution for pyarrow that do not apply:

build-1  | 1.) The wheel tags for pyarrow 16.0.0 are cp312-cp312-manylinux_2_28_x86_64 which do not match the supported tags of cp312-cp312-linux_x86_64:

build-1  | cp312-cp312-manylinux2014_x86_64

build-1  | ... 122 more ...

There is no pyarrow x86 version after pyarrow 12.0.1. I am using 2.21..0a0 pants version. This version seems to support python 312. I did change resolver_manylinux to manylinux_2_28 in pants.toml. This variable only applies for app.pex file does not impact the pex generation for FAAS. Please let me know if you need more information. pantsbuild/pants
