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

  1. Log in to the GeminiDB console.
  2. On the Instances page, click the target instance.
  3. In the navigation pane, choose Shard Management.

  4. Click Add Shard. On the displayed page, select the number of shards to be added.

    New shards are of the same specifications as existing shards. Once a shard is added, its specification cannot be changed.

  5. On the displayed page, confirm the shard configuration.

    • Pay-per-use
