AWS Lambda

Using swiftshadow with AWS Lambda normally raises an error because the cache mechanism won't work properly due to the read-only file permissions in the Lambda environment. To fix this, you can pass the cacheFolderPath parameter and set it to "/tmp" when creating a ProxyInterface instance.

from swiftshadow.classes import ProxyInterface

swift = ProxyInterface(cacheFolderPath="/tmp")

The /tmp directory in AWS Lambda is writable, allowing the cache to function correctly.

Disabling Caching

If you don’t want the caching behavior at all, consider using the QuickProxy function instead. It does not cache proxies, making it ideal for serverless environments like AWS Lambda.

from swiftshadow import QuickProxy

proxy = QuickProxy()
print(proxy.as_string())
