title: Hazelcast: Questions regarding multi-node consistency
body: <p>(I could not find a good source explaining this, so if it is available elsewhere, you could just point me to it)</p>
  
  <ol>
  <li><p>Hazelcast replicates data across all nodes in clusters. So, if data is changed in one of the nodes, does the node update its own copy and then propagate it to other nodes?</p></li>
  <li><p>I read somewhere that each data is owned by a node, how does Hazelcast determine the owner? Is the owner determined per datastructure or per key in the datastructure?</p></li>
  <li><p>Does Hazelcast follow "eventually consistent" principle? (When the data is being propagated across the nodes, there could be a small window during which the data might be inconsistent between the nodes)</p></li>
  <li><p>How are conflicts handled? (Two nodes update the same key-value simultaneously)</p></li>
