Consistent hashing solves a tricky problem: when scaling distributed systems, adding or removing nodes usually means rehashing almost all your data, causing massive data movement and downtime. Consistent hashing minimizes this by only moving a small fraction of keys when nodes change, making scaling smooth and efficient. The internet is full of high-level explanations of consistent hashing, but finding an actual implementation of the algorithm is rare. Finding a near-real implementation with nodes acting as cache partitions is even rarer. I built a hands-on system in Golang with a hash ring, an API to store and retrieve keys, add and remove Dockerized nodes, and real-time D3 visualization. It’s a small system, but it gives a clear view of how data moves and how nodes handle load. Check it out here: https://lnkd.in/dZvYNy5F
