Adding Instance Shards
Scenarios
This section describes how to add shards for an instance to suit your service requirements.
Precautions
- Shards can be added only for standard instances with cloud native storage.
- Adding shards will trigger fast load balancing, which may cause a request timeout for a few seconds. Enable automatic retry for services.
- You can only add shards when the instance status is Available or Checking restoration.
- A DB instance cannot be deleted when one or more shards are being added.
- After shards are successfully added, the system automatically expands the storage capacity (Number of new shards x Shard specification (GB)).
- Currently, shards can be added only for proxy cluster instances.
Procedure
- Log in to the Huawei Cloud console.
- In the service list, choose Databases > GeminiDB.
- On the Instances page, click the target instance.
- In the navigation pane, choose Shard Management.
