MySQL 8.0 Reference Manual Including MySQL NDB Cluster 8.0 CREATE RESOURCE GROUP Statement

    [VCPU [=] vcpu_spec [, vcpu_spec] ...]

vcpu_spec: {N | M - N}

CREATE RESOURCE GROUP is used for resource group management (see Section 5.1.16, “Resource Groups”). This statement creates a new resource group and assigns its initial attribute values. It requires the RESOURCE_GROUP_ADMIN privilege.

group_name identifies which resource group to create. If the group already exists, an error occurs.

The TYPE attribute is required. It should be SYSTEM for a system resource group, USER for a user resource group. The group type affects permitted THREAD_PRIORITY values, as described later.

The VCPU attribute indicates the CPU affinity; that is, the set of virtual CPUs the group can use:

Example VCPU specifiers (these are all equivalent):

VCPU = 0,1,2,3,9,10
VCPU = 0-3,9-10
VCPU = 9,10,0-3
VCPU = 0,10,1,9,3,2

The THREAD_PRIORITY attribute indicates the priority for threads assigned to the group:

ENABLE and DISABLE specify that the resource group is initially enabled or disabled. If neither is specified, the group is enabled by default. A disabled group cannot have threads assigned to it.


Resource group management is local to the server on which it occurs. CREATE RESOURCE GROUP statements are not written to the binary log and are not replicated.
