Comments by "Tony Zhou" (@ReflectionOcean) on "Consistent Hashing | Algorithms You Should Know #1" video.

  1. The core problem that consistent hashing trying to solve in the presence of frequent node addition and removal are: 1. even data distribution 2. minimum data movements 2 insights: 1. Distribute data to nodes on the hash ring rather than use modular function to minimize data movements because of changes of cluster memberships 2. Use virtual nodes to improve data distribution
