I learned this algorithim at university but didn't know how useful is this could in real-world scenarios. Nicely explained 👏.

What if after hasing for a server and a key, the hash value is the same, i.e, it refers to the same position in the circle?

[@IlyaDenisov]

What to do when multiple servers result in the same index after hashing? Could the biggest original value (IP:PORT) be discarded or that would cause issues?

[@sandeepy7ec288]

Excellent

Volume pretty low
