Adding Shards

Scenarios

This section describes how to add shards to a DB instance to suit your service requirements.

Precautions

• Currently, only standard instances in cloud native deployment mode can be added.
• 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 cluster instances.

Method 1

1. Log in to the GeminiDB console.
2. In the service list, choose Databases > GeminiDB Redis API.
