Consistent Hashing Explained: The What and the Why
Two nightd ago (and after a couple of beers), it took me about 10 minutes to explain what is consistent hashing and its benefits to a guy until he got the “aha” moment. But if I’d have to explain it in a more formal way and provide references I’d use Mathias’ post.
The simplicity of consistent hashing is pretty mind-blowing. Here you have a number of nodes in a cluster of databases, or in a cluster of web caches. How do you figure out where the data for a particular key goes in that cluster? […] Consistent hashing solves the problem people desperately tried to apply sharding to pretty nicely and elegantly.
