Upgrading a Minor Version

GeminiDB Redis API can be upgraded by installing patches to improve performance, release new features, or fix bugs.

After a new patch version involving performance improvement, new functions, or problem rectification is released, you can upgrade your instance to the latest version at a proper time based on service requirements.

If a new patch is released, you can upgrade your instance by clicking the upgrade button in the Compatible API column on the Instances page.

If the kernel version of your instance has potential risks or major defects, has expired, or has been brought offline, the system will notify you by SMS message or email and deliver an upgrade task during maintenance.

Precautions

  • Upgrade your instance once there is a new patch released.
  • If the database version is a risky version, the system prompts you to upgrade the database patch.
  • Upgrading the minor version of an instance will restart each node of the instance in sequence. When a node is being restarted, its services will be taken over by another node. Each takeover will interrupt services for 3 to 5 seconds. So, perform an upgrade during off-peak hours and enable automatic reconnection so that each node can be reconnected immediately after being restarted.
  • Upgrading basic components takes about 15 minutes. Upgrading data components takes about 1 to 2 minutes, which depends on how many nodes there are.
  • The system automatically checks the minor version of the instance. If the Upgrade Minor Version button does not exist on the console, the current minor version is the latest version.

Procedure

  1. Log in to the GeminiDB console.
  2. In the service list, choose Databases > GeminiDB Redis API.
  3. On the Instances page, locate the instance you want to upgrade and click Upgrade Minor Version in the Compatible API column.
