What is CAP Theorem in System Design?
CAP Theorem Explained With a Real Example!
Network partitions are not a rare event you can design around. They are going to happen, and the moment they do, your database cannot stay fully consistent and fully available at the same time. This one explains it with a real example: a photo app running one primary database and two replicas when the link between them drops.
You'll learn what AP and CP actually look like in production, why staying online is the right call for something like a like count, why blocking the operation is the only safe call for money, and why picking this deliberately is what keeps a system predictable under failure.
Like counts or account balances, which one would you let go briefly wrong? Tell us in the comments.
