[0002] With the development of multi-data center and multi-cloud environments, the registration center inevitably faces the problem of providing services across data centers. On the one hand, in most cases, financial business processing is completed in a single data center, that is, the registration center needs to fully support the financial business in this data center; on the other hand, when the data center cannot independently support business capabilities, it needs to be able to dispatch to other data centers to complete business processing. Therefore, the registration center is an indispensable and important component in modern distributed systems.

[0003] The existing registration center data query technology is to deploy a registration center in each data center, and through the data synchronization mechanism, replicate the data of different data centers to achieve the effect that each registration center has all the data. In actual applications, if the synchronization frequency is too high, it will occupy a lot of bandwidth and CPU, while if the synchronization frequency is too low, the real-time performance of the data is not enough, and each registration center has the data of all data centers, resulting in a huge amount of data, reduced registration center performance, and even unstable operation, resulting in low efficiency of data query.

The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc. The server can be an independent server, or it can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), and big data and artificial intelligence platforms.

[0061] Reference Figure 1 FIG. 1 is a flow chart of a data query method of a registration center alliance provided by an embodiment of the present invention. In this embodiment, the data query method of the registration center alliance includes:

[0062] S1. Create a registration center corresponding to each data center according to the pre-acquired business service node corresponding to the data center, and generate alliance information according to the registration address and priority corresponding to each registration center.

[0063] In an embodiment of the present invention, a data center refers to a physical or virtual location where data storage and computing resources are concentrated, a business service node refers to a server or virtual machine instance that provides services within the data center, each data node can be registered with a registration center to facilitate discovery and access by other services, each data center deploys a set of data centers, and each registration center provides services specifically for this data center, wherein the registration center refers to software in a distributed service system that is responsible for managing information related to each business service node.

[0064] In the embodiment of the present invention, the step of creating a registration center corresponding to each data center according to the pre-acquired business service node corresponding to the data center includes:

[0065] Configure a registry instance for each pre-obtained data center;

[0066] Configure the registration information of the registry center according to the registry center instance;

[0067] Mapping the registration information with the business service node to obtain a registration mapping relationship;

[0068] A registration center corresponding to the data center is created through the registration mapping relationship.

[0069] In detail, each data center has a unique identifier, and the business service node information of the data center includes the address, port, protocol and other information of the service node. For each data center, its corresponding registration center instance needs to be configured. The registration center instance is responsible for managing and coordinating the registration and discovery of each service instance, including service registration, configuring which services can be registered with the registration center; service discovery, configuring how to discover registered services; heartbeat and health check, configuring the heartbeat detection and health check mechanism of the service. Once the registration center instance is started and configured, the business service node needs to be registered with the registration center, and the registration information corresponding to each registration center needs to be configured based on the registration center instance.

[0070] Specifically, for the business service nodes of each data center, the corresponding registration information needs to be configured. The registration information includes the service name, address, port, protocol, etc., and then the service is registered to the registration center through the API interface of the registration center, and the registration information of the registration center is mapped with the business service node to obtain a registration mapping relationship. The registration mapping relationship can be a configuration file or a database record, which describes the relationship between each business service node and its corresponding registration center instance, thereby creating a set of registration centers corresponding to each data center based on the registration mapping relationship.

[0071] Furthermore, for a set of registration centers corresponding to each data center, if the registration centers of different data centers need to be connected to each other, the connection needs to be made based on the data of the registration centers. Therefore, the registration data of each registration center needs to be extracted.

[0072] In the embodiment of the present invention, the alliance information refers to the IP address information and priority information of each registration center, and the IP address information and the priority information constitute the alliance information.

[0073] In the embodiment of the present invention, the generating of alliance information according to the registration address and priority corresponding to each registration center includes:

[0074] Arrange all registration centers in descending order according to the priority corresponding to each registration center to obtain the first registration center sequence;

[0075] Arrange the registration addresses corresponding to each registration center from top to bottom according to the sequence order of the first registration center sequence to obtain a second registration center sequence;

[0076] Generate alliance information according to the second registration center sequence.

[0077] In detail, the priority of other registration centers is set for each set of registration centers through commands, and the priority is planned. First, all registration centers are sorted based on the priority of each registration center, and all registration centers are arranged in order from large to small priority. For example, the priority of registration center 1 is 90, the priority of registration center 2 is 80, and the priority of registration center 3 is 70. Then the first registration center sequence is {1,2,3}, and the registration address of each registration center is arranged from top to bottom based on the sequence order of the first registration center sequence. Then registration center 1 is arranged at the top and registration center 3 is arranged at the bottom, thereby obtaining the second registration center sequence, and then the alliance information of each registration center is generated according to the IP address and priority of the registration center, such as Figure 2 As shown in the figure, it is a schematic diagram of the alliance information formation. The data in the alliance information represents the priority from high to low from top to bottom. The registration center 1 is at the top layer, and the alliance information in the registration center 1 includes the IP addresses of the registration center 2 to the registration center n. In addition, the alliance information corresponding to the registration center 2 includes the IP addresses of the registration center 1 to the registration center n, and the IP addresses are arranged in order from high to low priority, so as to obtain the alliance information corresponding to each registration center.

[0078] Furthermore, the registration centers in different data centers are connected to each other to form a registration center alliance. The registration center alliances can query each other's data, but will not synchronize data with each other to ensure that the data centers do not affect each other.

[0079] S2. All registration centers are interconnected according to the alliance information to obtain a registration center alliance corresponding to the data center.

[0080] In the embodiment of the present invention, the registration center alliance refers to a registration center alliance formed by connecting all registration centers to each other. When a data center needs to be added, it is equivalent to adding a registration center cluster in the registration center alliance.

[0081] In the embodiment of the present invention, the step of connecting all registration centers to each other according to the alliance information to obtain the registration center alliance corresponding to the data center includes:

[0082] Selecting a registration center as a target registration center according to the order of the registration centers in the alliance information, and gathering the registration centers that are not selected as a registration center set;

[0083] Selecting a next registration center in the registration center set according to the order of the registration centers in the alliance information, and extracting the registration address of the next registration center;

[0084] receiving a connection request from the target registration center through the next registration center;

[0085] When the connection request is successfully received, the registration address of the target registration center is sent to the next registration center, and the process returns to the step of selecting the next registration center in the registration center set according to the order of the registration centers in the alliance information, until all the registration centers in the registration center set are selected;

[0086] When all the registration centers in the registration center set are selected, the method returns to the step of selecting a registration center as a target registration center according to the order of the registration centers in the alliance information, until all the registration centers are selected as target registration centers;

[0087] When all the registration centers are used as target registration centers, a registration center alliance corresponding to the data center is generated.

[0088] In detail, the registration centers in different data centers are connected to each other, that is, the IP address of another registration center (i.e., registration center 2 in the registration center set) is set to one registration center (i.e., the target registration center) through a command, and the target registration center sends a connection request to registration center 2. After the connection is successful, the target registration center tells registration center 2 its own IP address, and then repeats the above steps continuously, so that all registration centers are connected to each other and know the IP addresses of all registration centers.

[0089] Exemplarily, registration center 1 is selected as the target registration center, and registration centers 2 to n are taken as the registration center set. Then, registration centers 2 to n are selected in order of priority to be connected to registration center 1 until all registration centers are connected to registration center 1. Then, registration center 2 is selected as the target registration center, and registration centers 1 to n are taken as the registration center set. Then, registration centers 1 to n (except registration center 2) are selected in order of priority to be connected to each other until all registration centers are connected to registration center 2, thereby completing the connection between all registration centers in pairs to form a registration center alliance.

[0090] Specifically, as financial business grows, the amount of data and the number of users will also increase. Through flexible registration center expansion, enterprises can smoothly add new services and functions without affecting existing services. That is, when a data center needs to be added, it is equivalent to adding a registration center cluster within the registration center alliance, which has a very limited impact on the alliance's load. This leaves enough expansion space for the future business development of financial enterprises. For example, new registration center nodes can better distribute service requests, reduce the risk of single point failures, and support the registration and management of more service instances, thereby ensuring that the system can still maintain efficient operation in the face of growing transaction volume or user demand.

[0091] Furthermore, based on the registration center alliance, data query function can be realized. Under normal circumstances, the business capabilities that a data center can complete are all completed within the data center, and the registration center does not need to perform data queries across data centers. However, there may be special circumstances where the capabilities of the data center are insufficient to support business capabilities, and thus it is necessary to detect the capabilities of the data center for the next step of processing.

[0092] S3. When the preset target data center receives a data query request, it detects whether the service capability of the target data center meets the query requirements corresponding to the data query request.

[0093] In the embodiment of the present invention, when a data center receives a data query request, detecting whether its business capabilities meet the query requirements is a key step in ensuring efficient and reliable services. It provides the ability for multiple data centers to support each other, ensuring that the business can be completed in cooperation between each data center, maximizing the support capabilities of multiple data centers for the business, and is a nearly unlimited horizontal expansion capability.

[0094] In the embodiment of the present invention, the detecting whether the service capability of the target data center meets the query requirement corresponding to the data query request includes:

[0095] Determining a query requirement according to the data query request;

[0096] Simulating the target business capability of the target data center through the query demand;

[0097] Comparing the target service capability with the service capability of the target data center;

[0098] It is determined whether the target data center meets the query requirements corresponding to the data query request based on the compared business capabilities.

[0099] In detail, the query requirements corresponding to the data query request include query type, for example, range query, single query, aggregate query, etc.; data volume: the size of the data volume queried; response time requirements: the expectation of response time; resource requirements: such as computing, memory, storage, etc., and then simulate the business capabilities required by the target data center according to the query requirements corresponding to the data query request, such as processing power, server computing power and throughput; storage capacity, storage space and read / write speed; network bandwidth, data transmission rate; concurrent processing capability, the ability to process multiple queries at the same time; system load, current system load status, and collect the actual business capability data corresponding to the target data center, such as computing power, storage performance, network bandwidth, concurrent processing capability, so as to compare the target business capabilities in the simulation test with the actual business capabilities of the data center and analyze their matching degree.

[0100] Specifically, analyze whether the processing capacity of the target data center can meet the computing requirements of the query, storage capacity, storage and I / O performance are sufficient; network capacity, network bandwidth and latency meet the requirements; concurrent processing capacity, whether it can handle the expected number of concurrent requests, and then judge whether the target data center can meet the query requirements based on the comparison results, that is, analyze whether the actual business capabilities of the target data center meet the standards of the simulation requirements, compare key performance indicators such as response time, processing capacity, system load, determine whether it meets the requirements, check the performance of the system under high load and abnormal conditions, ensure stability and reliability, so as to effectively detect whether the business capabilities of the target data center can meet specific data query requests.

[0101] Furthermore, if the capacity of the current data center is insufficient to support the business capabilities, the registration center will initiate queries to other registration centers in turn according to the priority and address of the recorded data centers until the business capability requirements are met.

[0102] S4. When the business capability of the target data center does not meet the query requirements corresponding to the query request, query a registry that meets the query requirements in the registry alliance.

[0103] In an embodiment of the present invention, if the capacity of the current data center is insufficient to support the business capacity, the registration center will initiate inquiries to other registration centers in turn according to the priority and address of the recorded data center until the business capacity requirements are met; or if a serious failure occurs in a data center, making it difficult to complete most business processing, it is only necessary to switch the business processing to other data centers through the data center level to ensure the overall normal operation of the business, and the failure of a single registration center will not have any impact on other registration centers.

[0104] In the embodiment of the present invention, the step of searching the registry alliance for a registry that meets the query requirement includes:

[0105] Extracting the connection registration center corresponding to the target data center according to the registration center alliance;

[0106] Selecting a target connection registration center according to the priority of the connection registration center;

[0107] Determine whether the data center corresponding to the target connection registration center meets the query requirement;

[0108] When the data center corresponding to the target connection registration center does not meet the query requirement, the process returns to the step of selecting the target connection registration center according to the priority of the connection registration center until a registration center meeting the query requirement is found.

[0109] Specifically, when the target registration center is insufficient to support the business capability, the registration center is selected in order of priority, and it is determined whether the selected registration center can support the business capability. If it is still insufficient to support the business capability, the next registration center is selected until the selected registration center can support the business capability. Figure 3 As shown, it is a schematic diagram of selecting a data center. When registration center 1 is sufficient to support business capabilities, registration center 1 is directly used as the processing data center. When registration center 1 is insufficient to support business capabilities, registration center 2 is selected, and it is determined whether the registration center can support the business capabilities. If not, registration center 3 is selected. If registration center 3 can support the business capabilities, registration center 3 is used as the registration center that can meet the query requirements.

[0110] Specifically, when a data center has a serious failure, making it difficult to complete most business processing, such as Figure 3 If part of the capabilities of Data Center 1 is damaged, then Registry Center 1 will initiate queries to other Registry Centers in turn according to the priorities and addresses of other Registry Centers in the alliance. For example, Registry Center 2 will be queried first. If Data Center 2 has the ability to complete the corresponding business functions, Registry Center 2 will return the corresponding data, and the business functions required by Data Center 1 will be completed. Otherwise, Registry Center 1 will continue to initiate queries to Registry Center 3, relying on the capabilities of Data Center 3 to complete the required business functions.

[0111] Furthermore, when the service capability of the queried registration center meets the query requirement, the registration center queried at this time can be used to query the data corresponding to the data request.

[0112] S5. When the service capability of the queried registration center meets the query requirement, query the target data corresponding to the data query request through the queried registration center.

[0113] In an embodiment of the present invention, when the business capabilities of the queried registration center meet the query requirements, detailed information of the target data source, such as location, access interface, connection parameters, etc., is obtained from the registration center to query the target data corresponding to the data query request, wherein the target data refers to the data that actually needs to be retrieved from the data source, and the data query request usually includes the demand for certain specific information, such as customer records, sales data, log files, sensor data, etc. The target data may be stored in different databases, data warehouses, file systems or other storage media.

[0114] In the embodiment of the present invention, querying the target data corresponding to the data query request through the queried registration center includes:

[0115] Extracting request parameters corresponding to the data query request;

[0116] Connecting the data query request to the business service node corresponding to the queried registration center according to the request parameters;

[0117] The target data corresponding to the data query request is queried through the business service node.

[0118] In detail, the request parameters include detailed information of the target data source, such as location, access interface, and connection parameters. The interceptor can be used to extract the relevant parameters corresponding to the data query request, and then the query request is completed by sending a query request to the registration center. The query request contains the identification information of the service to be accessed (for example, service name, version, etc.). The registration center will return the business service node information related to the service. The business service node information may include the network address of the service node (such as IP and port) and other connection parameters. The service node information obtained from the registration center is used to establish a connection with the business service node, and the constructed data query request is sent to the business service node. The business service node processes the query request and returns the result, thereby obtaining the target data corresponding to the data query request.

[0119] The embodiment of the present invention avoids the single point problem of the registration center by deploying multiple registration centers, and avoids the synchronization of a large amount of data in normal times by performing data query within the alliance when necessary, thereby reducing the load of the registration center; at the same time, when necessary, the data of other data centers can be queried through the alliance, so that the business can be transferred between different data centers, improving the reliability of the business, ensuring that the business can be completed in cooperation between various data centers, and maximizing the support capabilities of multiple data centers for the business. Therefore, the data query method, device, equipment and medium of the registration center alliance proposed by the present invention can solve the problem of low data query efficiency.

[0120] like Figure 4 , which is a functional module diagram of a data query device of a registration center alliance provided by an embodiment of the present invention.
