How REST APIs support upload of huge data and long running processes | Asynchronous REST API

We are very glad to start the REST APIs made easy course with the very first video on fundamentals of REST APIs, HTTP Methods, taxonomy around REST APIs etc. We hope that you get some value out of this course and these concepts help you thrive in your jobs, interviews and help you become better software engineers every day. Here are few links that you might want to refer before or during the course:

I think what you have described here is the request/response pattern for long running jobs. This should NOT be confused with uploading a large file using HTTP, where you need to keep the connection alive until the content for that request is fully uploaded. If you send a 202 right away, the HTTP connection will be terminated and there is no way for the client to send the rest of the file. You can however, have multiple requests in parallel, where some are uploading different chunks of the file, while one request keeps polling the overall status. I think this is how youtube uploads work.

Very Nicely explained. Another good example of asynchronous flow is the life cycle of an order on an e-commerce site starting from placing of an order till it is delivered to the customer. Customer checks the status of his order on the e-commerce portal which in turn calls an Rest API in the backend to fetch that data.

As always, a simplified, easy to understand explanation. A logical next step would be to cover webhooks as a form of async APIs

[nandanp.c.]

Thanks for the video. Awesome explanation! Especially how you use all technical vocabulary to explain examples- long running operation/process, put/post api, Resource, Endpoint, latency, Asynchronous, Synchronus, token, fetch the data, user experience,

[himachal]

I think instead of file upload operation making an order is a better example.
The server can return a response with your req has been acknowleged.
Meanwhile a lot of operation can take place in bg for eg. Checking if the inventory is available fir that order, in which location the inventory is available, what would be the most optimal location to serve that order from etc.

Great video. I had one query:
In case of file upload, our api would be sending chunks of data continuously. Then how is it asynchronous?

[sajjad]

Hi ma'am, it would be great if you could make a video on the practical implementation of asynchronous APIs. And is there any relationship between async APIs and message queues? I mean can we use message queues to implement async APIs?

[vietanh]

Your channel is so simplified and easy to understand. But some video does not have subtitle. So I hope you can add subtitle for anyone can be easy to follow what you're saying. Thanks.

[ameeralikhan]

Great video, we can use it for bulk delete operation also.

[Sparshchokra]

its a HOT question in interview for me, Thanks for this video

[priteshugrankar]

Another good example would be withdrawing money from ATM vs withdrawing cash from bank after getting a token.

[hiteshgupta]

Thats a very rich content a big thankyou from society..

[shubhamjaiswal]

Thanks for this video, very nicely explained.

[MrPS]

Nicely explained. Thanks for this video👍👍👌

[iamnoob]

High Quality Content, lIked it, clicked like button

[sanathkumaru]

Thank you for such wonderful, precise content.

[RaunakShrivastava]

Hi Yogita, Thanks for making such an awesome content on System design. Can you please make on video on detailed explanation of communication between different components of a system with real-life example. Thanks again!

[aanadinatu]

Maam can you make an elaborate separate video for filtering and pagination . Like a detailed video with code snippets and examples

[sujitkumar]

Awesome tutorial for explaning Asynchronous call but It would have been better if you create one Asynchronous REST API through coding.

[kuberyadu]

Hey Yogita, this video is super helpful, I have a question, does asynchronous processing increase the efficiency of an api in any way?
