    Lindorm:Change the engine specification of an instance

    Last Updated:Sep 30, 2024

    You can change the engine specification of a Lindorm instance to meet your business requirements.

    Prerequisites

    A Lindorm instance is created and is in the Running state. For more information, see Create an instance.

    Usage notes

    • When you change the specification of a Lindorm instance, other changes cannot be performed on the instance at the same time. We recommend that you change the specification of your Lindorm instance during off-peak hours.

    • When you downgrade the engine specification of a Lindorm instance, make sure that the new specification can meet your business requirements.

    • When you evaluate whether the engine specification of the instance meets your current business requirements, you need to consider the number of read and write requests and other factors. If you require technical support when you evaluate the engine specification of the instance, submit a ticket.

    Procedure

    Follow the procedure corresponding to the series of your instance. For more information about how to view the series of the current instance, see View the series of an instance.

    Lindorm instance

    1. 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 instance that you want to manage or click Manage in the Actions column corresponding to the instance.

    2. In the Configurations section of the page, find the engine for which you want to change the specification.

      • Upgrade engine specification: In the Actions column corresponding to the engine, click Upgrade Specifications.

      • Downgrade engine specification: In the Actions column corresponding to the engine, choose image > Downgrade.

      Note

      The Upgrade Specifications and Downgrade options are available for LindormTable, LindormTSDB, and LindormSearch. For other Lindorm engines, you can change only parts of the specifications. The engine specifications that are displayed in the console takes precedence.

    3. On the Downgrade or Upgrade/Downgrade page, select a node specification for the engine. For more information about how to select a node specification for an engine, see Select a node specification and the number of nodes.

    4. Read and select the Terms of Service, and then click Buy Now.

      When the specification is being changed, the instance is in the Changing Specifications state. If the state of the instance changes to Running, the specification is changed.

      Note

      The time required to change the node specification is related to the number of nodes whose specification needs to be changed. In most cases, 2 to 10 minutes are required to change the specification of a single node. The required time increases if you want to change the specification of more nodes.
