NettetThe video discusses the issue of ordering events in a message queue or event bus with multiple topics, using examples of services posting response times and events like create, update, and delete. Enforcing order by timestamps or using distributed consensus algorithms like Paxos or Raft is mentioned as a solution. The use of logical clocks like … Nettet29. jan. 2024 · Read operations in ZooKeeper are not linearizable since they can return potentially stale data. This is because a read in ZooKeeper is not a quorum operation and a server will respond immediately to a client that is performing a read. ZooKeeper does this because it prioritizes performance over consistency for the read use case. NettetMulti-Paxos or Raft provides linearizability – an unambiguous description of one kind of "strong consistency" (applied to simple k/v stores without worrying about transactions). Let's take a look at an example in quorum-based systems, e.g. Cassandra with a replication factor of 3. client sets x=24. It sends the request to replica A and B. password recovery bundle 2012
