Cluster Overload Control

Scenario

If enabled, concurrent requests are dynamically controlled based on the resource pressure of master nodes to keep them and the cluster available.

Constraints

The cluster version must be 1.23 or later.

Enabling Overload Control

Method 1: Enabling it when creating a cluster

When creating a cluster of v1.23 or later, you can enable overload control during the cluster creation.
