Overload Control

It specifies whether the cluster overload control is enabled. If enabled, concurrent requests will be dynamically controlled based on the resource demands received by master nodes to ensure the stable running of the master nodes and the cluster.

Value Range

• false: Overload control is disabled.
• true: Overload control is enabled.

Default Value

false

Modifiable

Yes

Scope

CCE standard and CCE Turbo clusters

Suggestions

Enable overload control by default.

In particular scenarios, such as request burst over a short period of time, a cluster could still be overloaded even though overload control is enabled for it. In such cases, manage and control accesses to the cluster in a timely manner.
