After a new minor version for an engine is released, you can upgrade the engine of your Lindorm instance to the latest minor version in the Lindorm console with a few clicks. A minor version upgrade provides optimizations for the features of the existing minor version and additional new features.
Prerequisites
A Lindorm instance is created. For more information, see Create an instance.
Usage notes
When you upgrade the minor version for an instance, the instance must be restarted to make the upgrade take effect. We recommend that you upgrade the minor version during off-peak hours or make sure that your application can automatically reconnect to your instance.
The upgrade duration varies based on the number of instances that are deployed in a region. Many instances indicates a long upgrade duration.
Procedure
Log on to the Lindorm console.
In the upper-left corner of the page, select the region where the instance is deployed.
On the Instances page, click the ID of the target instance or click View Instance Details in the Actions column for the instance.
In the Configurations section, click the
icon in the Actions column for the engine that you want to upgrade.Click Upgrade Minor Version.
NoteYou can click the
icon corresponding to each engine to view the description of the engine version of the instance. In the Upgrade Minor Version dialog box, set Target Version to Latest Version or Stable Version.
ImportantLindormTSDB can be upgraded to the latest or a stable version, but other engines can only be upgraded to the latest version.
The operation of upgrading the minor version cannot be rolled back. We recommend that you upgrade the minor version to a stable version.
Click OK.
FAQ
Is the service affected during the minor version upgrade?
A network jitter may occur during the minor version upgrade. Therefore, we recommend that you perform the upgrade during off-peak hours.
When you upgrade LindormTable, the underlying files, and the compute engine, your service remains available, but read and write operations may experience jitter.
When you upgrade LindormTSDB or LindormSearch, the service may become disconnected or unavailable for a short period of time. Many engine nodes indicates a long upgrade duration.
You cannot perform other management operations, such as enabling a service or changing the instance configurations, during the minor version upgrade.
Are the previous SDK calls affected after the minor version upgrade?
No. The minor version upgrade does not remove or modify API operations.
Can I specify the destination version for a minor version upgrade?
LindormTSDB can be upgraded to either the latest or a stable version, whereas all other engines are upgraded to the latest version by default.
Do I need to follow a specific sequence if I upgrade multiple engines?
You cannot upgrade multiple engines at the same time. To upgrade multiple engines, complete the upgrade of one engine before upgrading the next engine.
Can I roll back the engine to a previous version after a minor version upgrade?
Because minor version upgrades cannot be rolled back, we recommend that you upgrade to a stable version.
