When you connect to a PolarDB for PostgreSQL cluster, an endpoint that is required to connect to the cluster. PolarDB for PostgreSQL provides cluster endpoints and primary endpoints. This topic describes how to view these endpoints in the console.
- Log on to the PolarDB console.
- In the upper-left corner of the console, select the region where the cluster is deployed.
- Find the cluster and click the cluster ID.
- On the Overview page, find the endpoints in the Endpoints section.
|Cluster endpoint||Each PolarDB cluster has a default cluster endpoint. An application can connect to multiple nodes by connecting to only one cluster endpoint. Cluster endpoints support read/write splitting. Write requests are forwarded to the primary node. Read requests are forwarded to the primary node or read-only nodes based on the load on each node.||Public and internal networks|
|Primary endpoint||A primary endpoint is used to connect to the primary node and supports read and write operations. If the primary node fails, the system fails over to the read-only node that is promoted to the primary node. Network traffic is routed to the new primary node through the primary endpoint.||Public and internal networks|
Internal and public endpoints
||You can connect to your PolarDB cluster by using the public endpoint to manage databases.|
