i always have this doubt when a cassandra node got a read request for local
quorum consistency does coordinator node asks all nodes with replicas in
that DC for response or just the fastest responding nodes to it who's count
satisfy the local quorum.
In this case RF is 3 Cassandra timeout during read query at consistency
LOCAL_QUORUM (2 responses were required but only 1 replica responded)....
does this mean coordinator asked only two replicas with fastest response
for data and 1 out of 2 timed out or coordinator asked all nodes with
replicas which means all three (3) and 2 out of 3 timed out as i only got
single response back.
