How long are the latency spikes when they occur? Have you investigated
compactions (nodetool compactionstats) during the spike?
Are you also seeing large latency spikes in the p95 (95th percentile)
metrics? p99 catches outliers, which aren't necessarily always cause for
alarm.
Are the
Is this Java 8 with the G1 garbage collector or CMS? With Java 7 and CMS,
garbage collection can cause delays like you are seeing. I haven’t seen that
problem with G1, but garbage collection is where I would start looking.
