Hello,
We are experiencing an issue where nodes a temporarily slow due to I/O

In general with LOCAL_QUORUM you should not see such an issue when one node
is slow. However, it could be because Client's are still sending requests
to that node. Depending on what client library you are using , you could
try to take that node out of your connection pool. Not knowing exact issue
