gp_resqueue_priority_cpucores_per_segment

gp_resqueue_priority_cpucores_per_segment

Specifies the number of CPU units allocated per segment instance. For example, if a Greenplum Database cluster has 10-core segment hosts that are configured with four segments, set the value for the segment instances to 2.5. For the master instance, the value would be 10. A master host typically has only the master instance running on it, so the value for the master should reflect the usage of all available CPU cores.

Incorrect settings can result in CPU under-utilization or query prioritization not working as designed.

The default values for the Greenplum Data Computing Appliance V2 are 4 for segments and 25 for the master.
