Hi,
Check the tombstone count, If is it to high, your query will be impacted.
If tombstone is a problem, you can try to reduce your "gc_grace_seconds" to
reduce tombstone count(Carefully because you use cross data centers).
Tchau,

I'm using JMX+Prometheus and Grafana.
JMX = https://github.com/prometheus/jmx_exporter
Prometheus + Grafana = https://prometheus.io/docs/visualization/grafana/
There are some dashboard examples like that:
https://grafana.com/dashboards/371
Looks good.
Thanks,

How is your Percent Repaired when you run " nodetool info" ?
Search for :
"reduced num_token = improved performance ??" topic.
The people were discussing that.
How is your compaction is configured?
Could you run the same process in command line to have a measurement?
Thanks,
Petrus Silva
