I have setup two data center with 5 nodes in each DC and each DC have connected two client application. I am using LWT with SERIAL consistency for some operation to get unique value from both DC.
2 DC, 1 Cluster,5 Nodes in each DC, NetworkTopologyStrategy, Replication factor : 3 when creating keyspace, Apache cassandra 3.11.4
I have following questions.
1. If one DC goes down then LWT query fail with error Not enough replicas available for query at consistency SERIAL. How can I resolve this scenario?
2. Option one works when I use LOCAL_SERAIL and set property 'allowRemoteDCsForLocalConsistencyLevel' at driver level. But in this case I am missing unique value from DC. How can I fix this?
Thanks in advance
