Is it possible at all that you may have a data hotspot if it's not hardware-related?


It does not seem so, The partition key seems well distributed and the queries update different keys.

We have dropped counter_mutation messages in the log :

COUNTER_MUTATION messages were dropped in last 5000 ms: 0 internal and 2 cross node. Mean internal dropped latency: 0 ms and Mean cross-node dropped latency: 5960 ms

Pool Name Active Pending Completed Blocked All Time Blocked ReadStage 32 503 7481787 0 0
CounterMutationStage     32       221        5722101 0                 0

The load could be too high ?

Thanks
