[0002] With the development of technology, financial-grade distributed databases usually adopt a multi-site and multi-center networking architecture to ensure the stability and reliability of their services and the high availability of each component. When a failure or abnormality occurs in the local main computer room, the business is required to be normally migrated to the same city or another place. For example, the main computer room (equivalent to the server) of a bank or financial institution is in Beijing, and the backup computer room is in Nanjing. Under normal circumstances, the Nanjing computer room is used as a copy to synchronize the business data of the Beijing main computer room. When a failure or abnormality occurs in the Beijing main computer room, the Nanjing backup computer room can smoothly take over the business of the Beijing main computer room.

[0033] Embodiment 1

[0034] Figure 1 A flowchart of a distributed database resource configuration method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of balanced configuration of distributed database resources. The method can be executed by a distributed database resource configuration device. The distributed database resource configuration device can be implemented in the form of hardware and / or software. The distributed database resource configuration device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0035] S110: Obtain data cluster information and server distribution information corresponding to the server switching task in the current distributed database.

[0036] Among them, the server switching task may refer to the task of switching the business data in a server to another server. Networking in a distributed database may refer to connecting multiple computers, servers, network devices, etc. into a network system so that they can communicate with each other and share resources. There are several data clusters and several servers distributed in the networking. Each data cluster requires a corresponding resource, such as a main component. Data cluster information may refer to the number of data clusters. Server distribution information may refer to the number of available servers. The core of the networking is the metadata database. Each library table in the metadata database records the master-slave relationship of each component in the networking, the role location information of each component, the operating status of each component, etc. In the present invention, all information related to the networking can be obtained by connecting to the metadata database.

[0037] Specifically, before executing the server switching task, the data cluster information and server distribution information corresponding to the current distributed database are obtained through the metadata database. For example, before the first switching, the obtained data cluster information and server distribution information are the initial installation information of the cluster.

[0038] Based on the above technical solution, "obtaining data cluster information and server distribution information corresponding to the server switching task in the current distributed database" may include: obtaining the server switching task of the current distributed database and establishing a connection relationship with the metadata database in the networking; obtaining the data cluster information and server distribution information corresponding to the current distributed database from the metadata database through the connection relationship.

[0039] Specifically, the server switching task of the current distributed database is obtained, and a connection relationship is established with the metadata database in the network before executing the server switching task. The number of data clusters in the network is obtained by querying the db_info table in the metadata database through the connection relationship, and recorded as m. The device_info table in the metadata database is queried through the connection relationship to obtain the IP list information of all servers, so as to confirm how many servers all data clusters are distributed on, and the number of servers in the network obtained is recorded as n.

[0040] S120: Determine target resource configuration information corresponding to the target server in the current distributed database based on the data cluster information and the server distribution information.

[0041] The target server may refer to an available server in the network. The target server may refer to a server distributed in all data clusters. The resource to be configured in the embodiment of the present invention may refer to a main component. The target resource configuration information may refer to the number of main components that should be on the target server in a balanced configuration.

[0042] Specifically, the ratio between the number of data clusters and the number of servers is determined as the target resource configuration information corresponding to the target server in the current distributed database.

[0043] For example, before obtaining the current resource configuration information, the existing switching interface is called to perform the first random master selection to execute the server switching task. This setting is to obtain the current resource configuration information after the switching operation, so that when the server switching action occurs, the balanced regulation of resources is achieved under the premise that the switching is carried out normally.

[0044] S130. Based on the current resource configuration information and the target resource configuration information corresponding to the target server, the target server is configured with resources to obtain a target distributed database with a balanced configuration of the target server.

[0045] Specifically, the current resource configuration information corresponding to the target server is limited within the range of the target resource configuration information, thereby achieving resource balanced configuration of the target server and obtaining a target distributed database with balanced target server configuration, thereby ensuring the same processing power of the target server and a balanced cluster distribution in the network.

[0046] It should be noted that, compared with the traditional switching solution, the technical solution of the embodiment of the present invention can ensure balanced distribution of resources after switching, avoid resource contention, and make resource occupancy predictable.

[0047] On the basis of the above technical solution, "configuring resources for the target server based on the current resource configuration information and target resource configuration information corresponding to the target server to obtain a target distributed database with a balanced configuration of the target server" may include: adjusting the current resource configuration information corresponding to the target server to the target resource configuration information to obtain a target distributed database with a balanced configuration of the target server.

[0048] The current resource configuration information is the resource configuration information corresponding to the target server when executing the server switching task.

[0049] Specifically, the current resource configuration information corresponding to the target server is compared with the target resource configuration information. If the current resource configuration information is greater than the target resource configuration information, the redundant main components are migrated. If the current resource configuration information is less than the required number of main components, that is, the target resource configuration information, the redundant main components on the remaining servers are migrated to this server. In this way, resource configuration is performed on the target server, and a target distributed database with a balanced configuration of the target server is obtained.

[0050] The technical solution of the embodiment of the present invention obtains the data cluster information and server distribution information corresponding to the server switching task in the current distributed database; determines the target resource configuration information corresponding to the target server in the current distributed database based on the data cluster information and the server distribution information; and configures the resources of the target server based on the current resource configuration information and the target resource configuration information corresponding to the target server, thereby obtaining a target distributed database with a balanced configuration of the target server. When the server switching action occurs, balanced configuration of resources is achieved under the premise that the switching is carried out normally, thereby improving the high availability of the distributed database.

[0051] Based on the above technical solution, the method also includes: obtaining reference resource configuration information corresponding to the target server in the target distributed database; verifying the reference resource configuration information based on the target resource configuration information to obtain a verification result; if the verification result is a configuration failure, prompting based on the verification result.

[0052] The reference resource configuration information may refer to the resource configuration information after the target server resource configuration. For example, the reference resource configuration information may refer to the number of main components after the target server resource configuration. The verification result may include configuration success and configuration failure.

[0053] Specifically, the reference resource configuration information corresponding to the target server in the target distributed database is obtained. If the reference resource configuration information and the target resource configuration information are the same, the verification result is a successful configuration. If the reference resource configuration information and the target resource configuration information are different, the verification result is a configuration failure, and a prompt is given based on the verification result so as to perform a secondary configuration, thereby improving the accuracy of resource configuration and further improving the high availability of the distributed database.

[0054] Embodiment 2

[0055] Figure 2 This is a flowchart of a distributed database resource configuration method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment describes in detail the process of determining target resource configuration information and resource configuration. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0056] S210: Obtain data cluster information and server distribution information corresponding to the server switching task in the current distributed database.

[0057] S220: Determine a ratio and a remainder of the ratio between the data cluster information and the server distribution information.

[0058] Specifically, the number m of data clusters is divided by the number n of servers to obtain a ratio (m / n) and a remainder of the ratio (m%n).

[0059] S230: If the remainder of the ratio is zero, the ratio is determined as the target resource configuration information corresponding to the target server in the current distributed database.

[0060] Specifically, if the ratio remainder (m%n) is zero, the ratio (m / n) is determined as the number of main components that should exist on the target server in the current distributed database, that is, the target resource configuration information corresponding to the target server.

[0061] S240: If the remainder of the ratio is not zero, determine the target resource configuration information corresponding to the target server in the current distributed database based on the ratio and a preset quantity threshold.

[0062] Among them, the preset quantity threshold is plus or minus one.

[0063] Specifically, if the ratio remainder (m%n) is not zero, there should be at most (m / n+1) main components and at least (m / n-1) main components on the target server.

[0064] S250: Based on the current resource configuration information and target resource configuration information corresponding to the target server, resources are configured for the target server to obtain a target distributed database with a balanced configuration of the target server.

[0065] Exemplarily, the switching module is called to perform the first switching to execute the server switching task, and then a connection with the metadata database is established to query the db_info table to obtain the number of main components currently existing on the target server, that is, the current resource configuration information. Sort the IP addresses of each target server from high to low according to the number of existing main components to obtain a server list. Traverse the server list of existing main components in positive order, and for the target server, if the number of existing main components is greater than the number of main components that should be on the target server, the redundant main components are migrated to the redundant main component list. If the number of existing main components traversed is exactly the number of main components that should be on the target server, stop traversing. Traverse the server list of existing main components in reverse order, and for the target server, if the number of existing main components is less than the number of main components that should be on the target server, select the main components with the difference in quantity from the redundant main component list and migrate them to this target server IP. If the number of existing main components traversed is exactly the number of main components that should be on the target server, stop traversing.

[0066] It should be noted that the technical solution of the embodiment of the present invention can also be applied to the switching process of various primary and standby data nodes in the database, and has universal applicability.

[0067] The technical solution of the embodiment of the present invention determines the ratio and the remainder of the ratio between the data cluster information and the server distribution information, and determines the targeted target resource configuration information for different situations, so as to accurately configure resources using the targeted target resource configuration information. In addition, the difference between the current resource configuration information and the target resource configuration information is used for sorting to obtain a server list, so as to traverse in forward and reverse order without traversing all servers, thereby improving the efficiency and accuracy of resource configuration and further improving the high availability of the distributed database.
