This topic describes how to add a tenant replica.
Procedure
Log on to the OceanBase Cloud Platform (OCP) console.
In the left-side navigation pane, click Tenants . The Tenant Overview page appears.
In the Tenants list, find the target tenant and click its name. The Tenant Details page appears.
Click Create Replica in the upper-right corner of the page.
In the dialog box that appears, specify Target Zone, Replica Type , and Resource Pool .
Parameter Description Target Zone The zone where the new replica exists. You can select a zone of the current cluster. Replica Type Valid values: Full-featured Replica, Read-only Replica, and Log Replica. - Full-featured Replica: A standard replica that provides complete data and features, including transaction logs, MEMTables, and SSTable. A full-featured replica can efficiently switch to become the leader to provide services.
- Log Replica: A replica that contains only logs. It does not have a MEMTable or SSTable. It provides log services for external applications and participates in log voting. It can facilitate the restoration of other replicas, but cannot upgrade to become the leader to provide database services.
- Read-only Replica: A replica that contains full logs, MEMTables, and SSTables. It does not participate in log voting as a member of the Paxos group. Instead, it works as an observer that synchronizes logs from the Paxos group members and then replays the logs locally.
Resource Pool Specify the unit specifications and the number of units. Click OK .
