    ApsaraMQ for Kafka:Upgrade the versions of instances

    Last Updated:Jul 27, 2023

    This topic describes how to upgrade the version of a ApsaraMQ for Kafka instance.

    Prerequisites

    The ApsaraMQ for Kafka instance is in the Running state.

    Background information

    • Major version upgrades

      A major version upgrade is an upgrade from one major version to another major version, such as the upgrade of a ApsaraMQ for Kafka instance from version 0.10.x to version 2.x.

      Important

      • ApsaraMQ for Kafka instances support major versions 0.10.x and 2.x. Major version 0.10.x includes minor versions 0.10 and 0.10.2. Major version 2.x includes only minor version 2.2.0.

      • The message storage format of instances running version 2.x is different from the message storage format of instances running version 0.10.x. Therefore, you cannot roll an instance back to version 0.10.x after the upgrade. Proceed with caution.

    • Minor version updates

      A minor version update is an update from one minor version to another, such as the update of a ApsaraMQ for Kafka instance from version 0.10 to version 0.10.2, or from version 0.10.2 to the 0.10.2 kernel-optimized version.

    Usage notes

    • Upgrades are free of charge, and upgraded versions are compatible with the existing SDKs and API operations.

    • To ensure your service continuity during the upgrade, make sure that your client supports automatic reconnection and can handle disconnections. By default, the client supports automatic reconnection.

    • We recommend that you purchase a test instance for upgrade verification before you upgrade your production instance.

    • We recommend that you perform the upgrade during off-peak hours.

    • After you upgrade the major version, upgrade the client version to keep the client and broker versions consistent. After you update the minor version, you do not need to upgrade the client version.

    • The duration for the upgrade of a major version depends on the size of the instance. The more nodes that an instance contains, the longer the upgrade duration is. The upgrade duration is about 25 minutes for an average-sized instance. During a major version upgrade, the nodes are upgraded one by one, and a certain amount of time is reserved to verify the upgrade of the previous node before the next node is upgraded. In normal cases, the upgrade will not interrupt the service or affect your business.

    • The duration for the update of a minor version depends on the size of the instance. The more nodes that an instance contains, the longer the update duration is. The update duration is about 15 minutes for an average-sized instance. During a minor version update, the nodes are updated one by one, and a certain amount of time is reserved to verify the update of the previous node before the next node is updated. In normal cases, the update does not interrupt the service or affect your business.
