Let’s break one of the biggest misconceptions about Consistent Hashing ⚡
Many engineers think that Consistent Hashing is a service that just solves your scaling problems and you use it whenever you hit some scale. This is not true at all.
Consistent Hashing is a very simple algorithm that helps you determine the ownership, that is it; and it does not take care of the data movement ⚡
It is so simple to implement CH that all it takes is an array and a binary search function for efficient implementation and can be plugged into any distributed storage system.
Pro tip: Whenever you come across any concept, first understand it, then think about its implementation. Being hands-on is a great way to know the nuances.
