Configure throttling

When a binlog instance handles a large amount of conversion and subscription data, it uses more resources such as the bandwidth, CPU, and memory, thereby compromising service stability. In this case, you can configure throttling for the binlog instance.

In OceanBase Cloud Platform (OCP), you can configure throttling for a binlog instance by using either of the following methods:

• Method 1: Go to the Binlog Cluster Overview page, find the target binlog instance in the Binlog Instance List section, click More in the Actions column, and select Configure Throttling .
• Method 2: Go to the Binlog Instance Overview page, and click Configure Throttling in the upper-right corner.

Prerequisites

Make sure that you have the following permissions:

• Resource Permissions : Binlog Service Maintenance permission
• Menu Permissions : Permission on the Binlog Cluster Overview menu of the Binlog Service

Procedure

The following procedure describes how to configure throttling for a binlog instance by using Method 2.

1. Log on to the OCP console.

2. In the left-side navigation pane, click Binlog Service . The Clusters page automatically appears.

3. On the Clusters page, find the target binlog cluster and click its name to go to the Binlog Cluster Overview page.

4. In the Binlog Instance List section, find the binlog instance for throttling configuration and click its name.

5. On the Binlog Instance Overview page, and click Configure Throttling in the upper-right corner.

6. In the dialog box that appears, configure throttling parameters and click OK .

   You can configure the following four throttling parameters for a binlog instance: Conversion Traffic (MiB/s) , Subscription Traffic (MiB/s) , Conversion RPS , and Subscription RPS . If any of the parameters is set to 0, the corresponding item is not throttled.
