Column name	Data type	Description
group_id	int	Unique ID of the workload group. Is not nullable.
name	sysname	Name of the workload group. Is not nullable.
importance	sysname	Is the relative importance of a request in this workload group. Importance is one of the following, with MEDIUM being the default: LOW MEDIUM HIGH Is not nullable. [!UWAGA] Importance only applies to workload groups in the same resource pool.
request_max_memory_grant_percent	int	Maximum memory grant, as a percentage, for a single request. The default value is 25. Is not nullable. [!UWAGA] If this setting is higher than 50 percent, large queries will run one at a time. Therefore, there is greater risk of getting an out-of-memory error while the query is running.
request_max_cpu_time_sec	int	Maximum CPU use limit, in seconds, for a single request. The default value, 0, specifies no limit. Is not nullable. [!UWAGA] For more information, see CPU Threshold Exceeded Event Class.
request_memory_grant_timeout_sec	int	Memory grant time-out, in seconds, for a single request. The default value, 0, uses an internal calculation based on query cost. Is not nullable.
max_dop	int	Maximum degree of parallelism for the workload group. The default value, 0, uses global settings. Is not nullable. [!UWAGA] This setting will override the query option maxdop.
group_max_requests	int	Maximum number of concurrent requests. The default value, 0, specifies no limit. Is not nullable.
pool_id	int	ID of the resource pool that this workload group uses.
group_min_memory_percent	int	Percentage of MIN_MEMORY_PERCENT, which is the minimum amount of memory reserved for the resource pool that cannot be shared with other resource pools. This value provides a guaranteed minimum for a group.
