Hi All In one of our cluster, read request with consistency "LOCAL_QUORUM" is going across DC. When we run query setting CONSISTECY to LOCAL_QUORUM in cqlsh, with tracing on, we see READ and digest request sent across to nodes on other DC. I have checked gossipinfo, peers table, nodetool status. No big gc pauses. Repairs are running fine. In logs we see a lot of messages informing us about slow queries running above 500 ms. Cluster is on Cassandra version 3.11.2 and this particular cluster has reported this issue. Any hint where I should see to further debug the issue would be of great help.
Regards Manish
