Thanks for the link, I hadn't seen that before.
It's unfortunate that they don't explain what they mean by "closest replica".
The nodes in the remote DC should not be regarded as "closest". Also, it's not
clear what the black arrows mean… the coordinator sends the read to all three
replicas, bu
quality reasons, you can use this consistency level in an offline datacenter to
prevent automatic connection to online nodes in other datacenters if an offline
node goes down.

Are you running a multi DC cluster? If yes do you have application in both data
centers/regions ?
On Tue,
I am seeing unexpected behavior: consistency level ONE increases read latency
99th percentile to ~108ms (95th percentile to 5ms-90ms) up from ~5ms (99th
percentile) when using LOCAL_ONE.
I am using DSE 5.0 with Datastax client 3.0.0. The client is configured with a
TokenAwarePolicy wrapping a D
d how do you know when that has happened)?
Note also QUORUM is a clear majority of replicas across both DCs. Some people
run 3 DCs with RF 3 in each and QUORUM to maintain strong consistency across
DCs even with DC failure.

e it would fail if there's
not a quorum in either DC (as would happen if one DC goes down). So it seems
like we are forced to use a lesser consistency such as ONE or TWO.
