Harsh reality: It will take you 10 years to realize how great our college curriculum is and how critical the core Computer Science subjects are.
Do not get misguided by these "EdTech cum SalesTech" startups and influencers. Everything at scale just boils down to

👇
- Operating system concepts: Mutex, Semaphores, Critical Sections, Thread, Sockets, etc
- Database Internals: Query optimization of Database
- Distributed Systems: Need I say anything here

- Computer Architecture: To understand why vertical scaling has a limit, page faults, cache lines
- Networking: Securing infra, optimizing routing, BGP, CDN, TCP, UDP, etc.
- Multimedia Processing: video encoding, codec conversions, image processing, RTMP, etc

Implementing Distributed Transactions ⚡ [in a gist]
Distributed Transactions are not theoretical; they are very well used in many systems. An example of it is 10-min food/grocery delivery.

✨ The UX we want is: Users should see orders placed only when we have one food item and a delivery agent available to deliver.
A key feature we want from our databases is atomicity. Our storage layer can choose to provide it through atomic operations or transactions.

We will have 3 microservices: Order, Store, and Delivery.
Important decision: Store services have food, and every food has packets that can be purchased and assigned.
Hence, instead of just playing with the count, we will play with the granular food packets while ordering.
