Force CPU usage in Dremio V23.1

vamsik · January 3, 2023, 5:17am

Is there any support key that forces the dremio to use maximum available CPU? when we run concurrent queries the CPU utilisation is staying at less than 25% while the query duration is increasing(when compared to individual run). want dremio to efficiently utilise CPU and bring down the runtime.

Thanks for helping,
Vamsi
