Witryna27 paź 2024 · Consistent hashing explained. Consistent hashing is used in distributed systems to keep the hash table independent of the number of servers available to minimize key relocation when changes of scale occur. In this article, I explain consistent hashing: what it is and why it is an essential tool in scalable distributed systems.
