[0029] Figure 1 This is a flow chart of a method for upgrading a cloud distributed database system provided according to an embodiment of the present invention. This embodiment is applicable to the case of performing version upgrades on a cloud distributed database system. The method can be executed by an upgrade device for a cloud distributed database system, and the upgrade device for a cloud distributed database system can be implemented in the form of hardware and / or software.

[0030] like Figure 1 As shown, the method of this embodiment may specifically include:

[0031] S110. In response to an upgrade triggering operation on the cloud distributed database system, determine a resource pool to be upgraded in the cloud distributed database system, take a snapshot of a component to be upgraded corresponding to the resource pool to be upgraded, and obtain a resource pool snapshot corresponding to the resource pool to be upgraded.

[0032] It should be noted that the cloud distributed database system is a data management system that combines distributed database technology with cloud computer technology. A cloud distributed database system is obtained by cloud-deploying the distributed database according to the cloud deployment architecture. The cloud deployment architecture places tenant nodes in containers for operation, and the container can realize on-demand allocation of resources. The deployment method corresponding to the cloud deployment architecture only needs to make the node installation file into a mirror to complete the container deployment. The cloud distributed database system may include multiple resource pools, and the resource pools may be distinguished according to different regions. Exemplarily, the cloud distributed database system includes a resource pool in region a, a resource pool in region b, and a resource pool in region c. A Kubernetes (k8s) cluster is deployed in each resource pool. The cloud distributed database system also includes a mobile cloud platform, which is used to manage and control the entire cloud distributed data architecture.

[0033] In this embodiment, in response to an upgrade trigger operation on the cloud distributed database system, the cloud distributed database system may be upgraded. The upgrade trigger operation may include a click operation on the version information of the target upgrade version on the user interface. Exemplarily, the user interface displays the version information of the current upgradeable version corresponding to the cloud distributed database system, and the version information includes the version number and the generation date. By clicking on the version information, the upgrade of the cloud distributed database system is triggered.

[0034] In a specific implementation, when performing an upgrade operation on a cloud distributed database system, each resource pool in the cloud distributed database system may be determined as a resource pool to be upgraded. Alternatively, a specific implementation method of determining a resource pool to be upgraded in a cloud distributed database system may be: obtaining a switch identifier of a grayscale switch corresponding to each resource pool in the cloud distributed database system; for each resource pool, when the switch identifier corresponding to the resource pool is a preset open identifier, determining the resource pool as a resource pool to be upgraded.

[0035] It should be noted that the configuration items of the grayscale switch can be configured for the resource pool in the cloud distributed database system. The upgrade method of each resource pool is determined by controlling the switch identifier of the grayscale switch. For each resource pool, the switch identifier of the grayscale switch is different, and the corresponding upgrade method is different. Exemplarily, for a resource pool whose switch identifier of the grayscale switch is an open identifier, a snapshot can be generated for the resource pool, and after upgrading the snapshot, the resource pool is replaced to achieve an upgrade of the resource pool. For a resource pool whose switch identifier of the grayscale switch is a closed identifier, the business processing of the resource pool can be suspended, and the resource pool can be directly upgraded.

[0036] In this embodiment, when upgrading the cloud distributed database system, the switch identifier of the grayscale switch corresponding to each resource pool in the cloud distributed database system can be obtained. The resource pool represented by the switch identifier of the grayscale switch being turned on can be determined as the resource pool to be upgraded. Specifically, for each resource pool, it is determined whether the switch identifier corresponding to the resource pool is consistent with the preset open identifier. If they are consistent, the resource pool is determined as the resource pool to be upgraded. Exemplarily, the preset open identifier can be true, 1, or enable. The close identifier of the grayscale switch can be false, 0, or disable. This embodiment uses the switch identifier of the grayscale switch to quickly and effectively determine the resource pool to be upgraded that needs to be snapshotted.

[0037] In a specific implementation, a snapshot can be taken of the components to be upgraded corresponding to the resource pool to be upgraded, and the snapshots of each component to be upgraded form a resource pool snapshot corresponding to the resource pool to be upgraded. Specifically, a snapshot is taken of the components to be upgraded corresponding to the resource pool to be upgraded to obtain a resource pool snapshot corresponding to the resource pool to be upgraded, including: taking snapshots of the component images in the image library corresponding to the resource pool to be upgraded, the gateway service components in the resource pool to be upgraded, the original database instance, and the cluster management service components, respectively, to obtain a resource pool snapshot corresponding to the resource pool to be upgraded.

[0038] It should be noted that each resource pool includes a metadata library, a gateway service component (GDB-WEB), an original database instance, and a cluster management service component (operator). Each resource pool is associated with an image library, which contains component images.

[0039] In this embodiment, a snapshot may be taken of the component image in the image library corresponding to the resource pool to be upgraded to obtain a first snapshot, a snapshot may be taken of the gateway service component to obtain a second snapshot, a snapshot may be taken of the original database instance to obtain a third snapshot, and a snapshot may be taken of the cluster management service component to obtain a fourth snapshot. The first snapshot, the second snapshot, the third snapshot, and the fourth snapshot constitute a resource pool snapshot.

[0040] This embodiment takes snapshots of different components in the resource pool to be upgraded to obtain a resource pool snapshot that can completely replace the resource pool to be upgraded, thereby facilitating subsequent version upgrade processing.

[0041] S120: Perform upgrade processing on the resource pool snapshot to obtain a target upgrade snapshot corresponding to the resource pool snapshot.

[0042] In this embodiment, the resource pool snapshot can be sent to the operation and maintenance terminal, so that the resource pool snapshot can be upgraded by the operation and maintenance terminal to obtain a target upgraded snapshot. Specifically, the snapshot obtained by the upgrade process can be used as the target upgraded snapshot corresponding to the resource pool snapshot.

[0043] In order to ensure the stability and effectiveness of the target upgrade snapshot, the resource pool snapshot can be optionally upgraded to obtain the target upgrade snapshot corresponding to the resource pool snapshot. The specific implementation method can also be: performing version upgrade on the resource pool snapshot and performing version testing on the upgraded resource pool snapshot; if the test passes, the upgraded resource pool snapshot is used as the target upgrade snapshot.

[0044] In this embodiment, the resource pool snapshot can be upgraded according to the pre-acquired version information. In order to ensure the stability and effectiveness of the upgraded resource pool snapshot, the resource pool snapshot obtained after the version upgrade can be tested. If the test passes, it means that the upgraded resource pool snapshot meets the operation requirements, and the upgraded resource pool snapshot can be directly used as the target upgrade snapshot.

[0045] Furthermore, it also includes: if the test fails, based on the test data generated during the version test, generating a target test log corresponding to the resource pool snapshot after the upgrade, and displaying the target test log.

[0046] In this embodiment, if the test fails, in order to facilitate the operation and maintenance personnel to check and find problems, the test data generated during the version test can be used as the target test log corresponding to the target upgrade snapshot. The target test log is sent to the operation and maintenance terminal and displayed on the operation and maintenance terminal.

[0047] After upgrading the resource pool snapshot, in order to ensure the stability and security of the upgraded resource pool snapshot, this implementation tests the upgraded resource pool snapshot and uses the resource pool snapshot that passes the test as the target upgraded snapshot, thereby ensuring that the target upgraded snapshot can run normally.

[0048] S130: Based on the target upgrade snapshot, update the resource pool to be upgraded in the cloud distributed database system to complete the upgrade of the cloud distributed database system.

[0049] In this embodiment, the resource pool to be upgraded in the cloud distributed database system can be replaced with the target upgrade snapshot corresponding to the resource pool to be upgraded to complete the upgrade of the resource pool to be upgraded. After each resource pool in the cloud distributed database system completes the upgrade operation, the upgrade of the cloud distributed database system is completed.

[0050] Optionally, based on the target upgrade snapshot, updating the resource pool to be upgraded in the cloud distributed database system includes: obtaining the current database instance in the resource pool to be upgraded, updating the target upgrade snapshot based on the current database instance; replacing the resource pool to be upgraded with the updated target upgrade snapshot.

[0051] It should be noted that since the resource pool to be upgraded has been executing business processing during the resource pool snapshot upgrade process, the database instance can be migrated to make the database instance in the target upgrade snapshot match the database instance in the resource pool to be upgraded at the current moment.

[0052] The current database instance is the database instance in the resource pool to be upgraded at the moment when the target upgrade snapshot is obtained.

[0053] In this embodiment, the current database instance in the resource pool to be upgraded can be obtained, and the current database instance is compared with the instance snapshot included in the target upgrade snapshot. If the current database instance matches the instance snapshot included in the target upgrade snapshot, the resource pool to be upgraded can be directly replaced with the updated target upgrade snapshot. If the current database instance does not match the instance snapshot included in the target upgrade snapshot, the current database instance can be replaced with the instance snapshot included in the target upgrade snapshot, and the resource pool to be upgraded can be replaced with the target upgrade snapshot after the instance snapshot is replaced.

[0054] In this embodiment, by comparing the instance snapshot in the target upgrade snapshot with the current database instance, it is ensured that the database instance in the target upgrade snapshot matches the database instance in the resource pool to be upgraded at the current moment.

[0055] The technical solution of the embodiment of the present invention, in response to the upgrade trigger operation of the cloud distributed database system, determines the resource pool to be upgraded in the cloud distributed database system, takes a snapshot of the to-be-upgraded component corresponding to the resource pool to be upgraded, and obtains the resource pool snapshot corresponding to the resource pool to be upgraded; obtains the target upgrade snapshot corresponding to the resource pool snapshot by performing upgrade processing on the resource pool snapshot, so that the business processing of the resource pool to be upgraded is not affected during the upgrade processing; and based on the target upgrade snapshot, updates the resource pool to be upgraded in the cloud distributed database system to complete the upgrade of the cloud distributed database system. The technical solution provided by this embodiment completes the upgrade of the cloud distributed database system by performing upgrade processing on the resource pool snapshot, so that during the upgrade processing, there is no need to suspend the business processing operation of the resource pool to be upgraded, which can improve the efficiency of the cloud distributed database system in processing business.

[0056] The above describes in detail the embodiments corresponding to the upgrade method of the cloud distributed database system. In order to make the technical scheme of the method further clear to those skilled in the art, a specific application scenario is given below.

[0057] In this embodiment, the cloud distributed database system includes resource pool 1, resource pool 2 and resource pool 3, the mobile cloud platform is connected to the three resource pools, and the mobile cloud platform includes a mobile cloud ordering page, a mobile cloud console and a mobile cloud collaboration platform. A k8s cluster is deployed in each resource pool, and each resource pool contains a corresponding metadata library, a gateway service component, an original database instance and a cluster management service component. Each resource pool corresponds to an image library for storing the component images required in the resource pool.

[0058] In order to describe the upgrade process of the cloud distributed database system in detail, please refer to Figure 2. For each resource pool, it can be determined whether the grayscale switch is turned on. When the grayscale switch is turned on, the resource pool is used as the resource pool to be upgraded, and a resource pool snapshot corresponding to the resource pool to be upgraded is generated. The resource pool snapshot contains all components in the resource pool to be upgraded. For example, if the grayscale switches of resource pool 1, resource pool 2, and resource pool 3 are all turned on, snapshot 1, snapshot 2, and snapshot 3 are generated. After the resource pool snapshot is generated, the resource pool snapshot can be sent to the operation and maintenance terminal, and the operation and maintenance personnel upgrade the resource pool snapshot to obtain the target upgrade snapshot, and perform version testing on the target upgrade snapshot; at the same time, the resource pool to be upgraded corresponding to the target upgrade snapshot provides library services normally. When the target upgrade snapshot passes the test, the target upgrade snapshot can replace the resource pool to be upgraded and provide services externally; the resource pool to be upgraded can be retained for a preset period of time and then deleted to ensure that the upgraded target upgrade snapshot can run stably, and then the original resource pool to be upgraded can be deleted. After all resource pools in the cloud distributed database system have been upgraded, it means that the cloud distributed database system has been upgraded, and the grayscale switches corresponding to each resource pool can be turned off.

[0059] This embodiment realizes the rapid upgrade of the mobile cloud distributed database, reduces the operational risk of the upgrade, and improves the upgrade efficiency.
