Design a video processing pipeline for a Video Streaming service starting from upload, storage, process, post-process, on-demand processing, and caching. The core of this problem statement is to design the system in such a way that the processing of videos post upload is done with massive parellization.
The problem statement is something to start with, be creative and dive into the product details and add constraints and features you think would be important.
- ability to processes thousands of videos in parallel
- design a robust video upload flow
- make your high-level components operate with high availability
- ensure that the data in your system is durable, not matter what happens
- define how your system would behave while scaling-up and scaling-down
- make your system cost-effective and provide a justification for the same
- describe how capacity planning helped you made a good design decision
- think about how other services will interact with your service
- ensure the data in your system is never going in an inconsistent state
- ensure your system is free of deadlocks (if applicable)
- ensure that the throughput of your system is not affected by locking, if it does, state how it would affect
Create a design document of this system/feature stating all critical design decisions, tradeoffs, components, services, and communications. Also specify how your system handles at scale, and what will eventually become a chokepoint.
Do not create unnecessary components, just to make design look complicated. A good design is always simple and elegant. A good way to think about it is if you were to create a spearate process/machine/infra for each component and you will have to code it yourself, would you still do it?
To understand the nuances and internals of this system, understand
- how CDN streams the video
- how on-demand video optimization works
- how caching strategy is designined for video streaming service
- CDN for video streaming
- designing a robust upload flow of video
- parellel processing of a complex workflow
