My Cassandra ring spans two DCs. I use local quorum with replication factor=3. I do a write in DC1 with local quorum. Data gets written to multiple nodes in DC1. For the same write to propagate to DC2 only one copy is sent from the coordinator node in DC1 to a coordinator node in DC2 for optimizing traffic over the WAN (from what I have read in the Cassandra documentation)
Will a Wan hiccup result in a Hinted Handoff (HH) being created in DC1's coordinator for DC2 to be delivered when the Wan link is up again?
