What I Learned Building a Redis Clone in C++
A few weeks ago I was studying backend development from first principles. Not frameworks, not tutorials that skip the hard parts — actual fundamentals. How does data get stored? How does a server talk to a client? What even is a database at its core?
That's when I came across Redis for the first time.
I was reading about caching and kept seeing Redis mentioned everywhere. I looked it up and found out it's just a key-value store — you give it a key, it gives you back a value. Fast. Simple. Used by Twitter, GitHub, Snapchat.
And I thought: how hard can it be to build something like that?
