Hi team, we see unusual CPU utilization spikes on the Druid query node twice recently (2 weeks apart); we are using Druid version 24. I am wondering if there are any known issues related to CPU utilization that got fixed in newer versions? Thank you!

There have been many improvements since 24. Is this workload related? Any particular queries or ingestion tasks that align with the timing of the high CPU usage? Are you emitting metrics? Metrics analysis can help pinpoint the issue.

@Sergio Ferragut Thank you Sergio. We are still analyzing what happened, but it does seem that there was an ingestion task happening while the spike happened. We will check if we are emitting metrics and enable them if not. Thanks.
