Key concept (Slides not available)

  • Consistency: each node has to be updated about changes in the Networks
  • User talks to an interface, NOT to a single node
  • But sometimes user could query the interface and read the prev values (w.r.t the propagation)
  • How to solve it? Block the user from reading (under Consistent/Linearizabilty)
  • Other way: INCONSISTENT —> User can read even if the information is propagated anywhere
  • Case: multiple users. Ex. 1 write and 1 read.
  • Consistent => Fully centralized
