Hi Druids! Hope you're all well. I had some questions for druid_processing_numThreads. We are seeing the average CPU for the historical is around 10-20, reaching a max of 30% during the day. The value for the druid_processing_numThreads currently is set to 20 for our 16core, 128Gb box. The docs recommend keeping it at : numcores - 1. But since we're in such under utilisation, I wanted to increase the number of threads to about 40. Was wanting to know, how others have the config for the same. If you have the following numbers kindly comment below with a one liner for your experience of the same. This would specifically be for the case of running separate servers for Druid, not single server deployments. Kindly add any of the following below : CPU cores druid_processing_numThreads Average CPU Utilisation P99 Query time Any major experience upsides/downsides. Thank you guys for your consideration and time.
