Connecting to the GD
Last updated:2025-07-25 15:50:49
This document introduces operations related to viewing the cluster addresses of the global database (GD) and connecting to the GD.
Prerequisites
Introduction of GD Connection Address
In the GD architecture, both the primary cluster and each secondary cluster provide independent cluster addresses. You can select the cluster address that is geographically closest to the region where the application is located to quickly access the GD. The system supports an automatic read-write separation mechanism, where read requests are generally sent to the local cluster, while write requests are all forwarded to the primary cluster for execution.
Viewing the Cluster Address
1. Log in to the TDSQL-C for MySQL console.
2. Click GDN in the left sidebar.
3. Find the target GD and click Details under the Read-write Address field.
4. In the pop-up sidebar, cluster address details can be viewed.
Connecting to the GD
Applications in different regions can connect to the GD using the cluster address of the local cluster, and the GD will automatically handle read-write separation. The method for connecting to the GD is the same as that for connecting to a cluster. For details, see Connecting to a Cluster.
