Async AWS Lambda Integration for Media Rendering with Python

[steinathan]

Feature Request 🛍️

The current Python Lambda package for remotion_lambda python appears to be blocking and lacks native support for asynchronous execution. This limits its integration with async-driven environments and frameworks, which are increasingly common in modern Python applications. Adding support for async Lambda functions would enhance its usability and improve compatibility with contemporary architectures.

Use Case

• Support for non-blocking, asynchronous execution in the Python Lambda package.
• Enable better compatibility with async workflows, such as asyncio or frameworks relying on asynchronous I/O.

Possible Solution

• Modify the Lambda function execution model to allow for async functions and non-blocking behavior.
• Consider adding configuration options for handling async functions or integrating with asyncio-based workflows.
• Ensure backward compatibility with existing blocking functions for users not using async operations. (AsyncRemotionClient and RemotionClient)

I am happy to make contributions if the proposed solution is acceptable. Let me know if further discussion or implementation is needed!

Thanks for this suggestion!

That makes a lot of sense for sure.
I think we can do this by using InvocationType = 'Event' in here:

remotion/packages/lambda-python/remotion_lambda/remotionclient.py

Lines 106 to 108 in 9db28ef

	response = client.invoke(
	FunctionName=function_name, Payload=payload, )
	result = response['Payload'].read().decode('utf-8')

(referring to the docs, very bottom of the page: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/lambda/client/invoke.html#)

Thanks for offering to make a contribution, I'd be very happy if you'd try that!
