Asynchronous REST API(s)

Building rest API is possibly one of the common activity which might have seen in any recent modern applications. It might not be that difficult to write a restful api than scaling it. Horizontal scaling with growing number of incoming request is always be the challenge. Though there are many modern mechanism are available to perform horizontal scaling of any restful API(s). If you ask any engineer now days. Suggestion would come as follows.

1. Need to follow Microservices architectural pattern, so that individual services can be deployed multiple times to handle load.
2. Rest API should be hosted with a server which is scalable itself and can handle millions of request.
3. Use Kubernetes based deployment of service pods with multiple replication factor.
4. Use of serverless framework (like - AWS lambda, Azure Function) if cloud deployment is a choice.
5. Use the language (like - node.js) which are async in nature or using possibly Go.

there could be few more as well... But someone has to realize it's not only the deployment strategy or load balancing would actually help to scale one rest api. Rest API code itself needs to be capable of handling multiple request at once. If the Rest API itself is written as synchronous manner then it would be bit difficult for handling such request at scale. And particularly if the choice of programming language is Python then it has more challenges than normal. Let's see how we can we write such rest API(s) :

Synchronous Rest API :

• InfoSvcSync - API is actually has been written to handle incoming request synchronously.
• It has been written using Falcon library.
• Similarly it can be written using Flask library.
• Sample request and response looks to be something like as per below :

Server :

• If you notice each request is taking quite a bit of time to respond. That can be tracked based on the correlation id.
• Because of the response delay client also actually timed out while waiting on other task to get finish.

Asynchronous Rest API With aiohttp library:

• It's one of the other way of writing rest api which would perform async request and response.
• With help of aiohttp library we should be able to handle many more request than sync call.
• If you notice request and response, you would notice pretty instantaneous.

• There is a very good read on this topic which I recently discovered in here https://medium.com/radix-ai-blog/performant-http-with-aiohttp-in-python-3-756580e54eff
• It's has been claimed that with asyncio and uvloop anyone can gained more performance.

From the internal implementation point of view there would be only 2 set of differences between Sync and Async rest API. One of the type uses - WSGI(Web Server Gateway Interface) and other one ASGI (Asynchronous Server Gateway Interface). Implementation details can be found in here - https://buildmedia.readthedocs.org/media/pdf/asgi/latest/asgi.pdf

Now, the question is what would happen of all the Synchronous implementation which has already been done. How to scale those without doing much modifications in code. Answer would be

1. You can introduce a async layer in your service architecture. For an example : Celery This gives a proper asynchronous task based system which would actually helps in performing async communication between services with correlation id. One of the sample implementation can be seen in here : https://github.com/sughosneo/taskmgmt

2. Or, if task based implementation could be overkill trade off based on the user base and time constraint. Then you can introduce a think async language layer like node.js for your metadata handling and shift the core responsibility to your autonomous python application services. So that most of the transactions would get taken care by the fast asyn rest API layer.

But one thing you would require to keep in mind if you are planning to adopt or use Async Web frameworks for your API or web developement you would need to make sure it has proper eco-system around it supporting asynchronous functionalities or coroutines. For an example : It should have proper Auth library for authentication purpose or could ORM libraries for any databases. In such scenarios I would suggest to take a peek of list of supported aio-libs in https://github.com/aio-libs

Then ofcourse above listed points could be useful extension of this coding exercise which can also be used to enhance the scalability.
