Returns the stored workload group configuration in SQL Server. Each workload group can subscribe to one and only one resource pool.

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 Note: Importance only applies to workload groups in the same resource pool.

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.
request_max_memory_grant_percent int Maximum memory grant, as a percentage, for a single request. The default value is 25. Is not nullable.

Note: 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.

Note: 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.

Node: 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.
external_pool_id int Applies to: SQL Server 2016 through SQL Server 2017.

ID of the external resource pool that this workload group uses.

Remarks

The catalog view displays the stored metadata. To see the in-memory configuration, use the corresponding dynamic management view, sys.dm_resource_governor_workload_groups (Transact-SQL).

The stored and in-memory configuration can be different if the Resource Governor configuration has been changed but the ALTER RESOURCE GOVERNOR RECONFIGURE statement has not been applied.
