CREATE WORKLOAD GROUP

Description

This statement is used to create a workload group. Workload groups enable the isolation of cpu resources and memory resources on a single be.

Syntax

CREATE WORKLOAD GROUP [IF NOT EXISTS] "rg_name"
[FOR <compute_group>]
PROPERTIES (
    `<property>`
    [ , ... ]
);

Parameters

1. <compute_group>

   Specifies the compute group that the workload group is bound to.

   • Cloud (storage-compute decoupled) mode: The FOR <compute_group> clause must be explicitly specified. Omitting it raises: Must specify compute group via 'FOR <compute_group>' in cloud mode.
   • Non-cloud (storage-compute coupled) mode: The FOR <compute_group> clause is optional. The value here actually refers to a resource group (Tag) rather than a real compute group — the grammar is shared with cloud mode purely for consistency. When omitted, it defaults to the default resource group (default).

2. <property>

   <property> format is <key> = <value>, and <key>'s specific optional values can be referred to workload group.

Examples

1. Create a workload group named g1 (non-cloud mode: bound to the default resource group):

    create workload group if not exists g1
    properties (
        "max_cpu_percent"="10%",
        "max_memory_percent"="30%"
    );

2. Create a workload group named g1 bound to compute_group_a (the clause is required in cloud mode):

    create workload group if not exists g1 for compute_group_a
    properties (
        "max_cpu_percent"="10%",
        "max_memory_percent"="30%"
    );
