Headquarters information and branch office information are distributed across different databases; if there are updates at headquarters, all branches need to be notified to synchronize these updates.

[0003] Currently, the synchronization update methods used are either through a message queue (MQ) or by traversing all distributed databases for updates. However, when there is a large amount of update information, sending large amounts of data via an MQ message queue has low reliability and high performance requirements; performing multiple queries and updates by connecting to all distributed databases consumes significant update resources; resulting in low update efficiency for branch offices synchronizing updates with headquarters.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0050] With the rapid development of information technology, the amount of data generated by various business operations is increasing. Using distributed databases to store this data is suitable for distributed, modular system architectures, and can improve system reliability, availability, and performance. However, with distributed databases, head office information and branch office information are distributed across different databases. If there are updates at head office, all branches need to be notified for synchronization, which is cumbersome.

[0051] Currently, the synchronous update methods used are either through a message queue (MQ) or by iterating through all distributed databases. When updating a large amount of information, using an MQ to send large amounts of data results in low reliability and high performance requirements; while iterating through all distributed databases for multiple queries consumes significant resources and is unsuitable for online scenarios. The current synchronous update methods also tend to lead to low update efficiency when branch offices synchronize updates with headquarters.

[0052] Based on this, embodiments of this application provide an information synchronization update method, apparatus, device, and storage medium. The method is applied to a server, generating unitized text based on the association between the head office and branch offices and the head office's update information. This unitized text is then merged to obtain a data file, where the unitized text includes update information from all branch offices. The data file is processed line by line using database sharding and table partitioning rules to obtain the target branch office's update information. The target distributed database for the target branch office is determined based on its update information. Finally, the target distributed database is synchronized and updated based on the target branch office's update information. In this way, the data file containing update information from all branch offices is processed line by line to obtain the target branch office's update information. The database containing the branch office's update information is located based on this information to perform the information synchronization update. This method is simple and fast, improving the efficiency of information synchronization updates.

[0053] To facilitate understanding of the technical solutions provided in the embodiments of this application, the following description, in conjunction with the accompanying drawings, illustrates an information synchronization and updating method, apparatus, device, and storage medium provided in the embodiments of this application.

[0054] See Figure 1 , Figure 1 This is a flowchart illustrating an information synchronization and update method provided in an embodiment of this application. The method specifically includes steps S101-S105. It should be noted that this method can be applied to a server or system, and this embodiment does not limit its application.

[0055] S101: Generate unitized text based on the relationship between the head office and branch offices and the head office update information, wherein the unitized text includes update information of all branch offices.

[0056] For large volumes of data related to headquarters and branch offices, a database sharding and table partitioning approach was used. (See also...) Figure 2 , Figure 2 This application provides a schematic diagram of a server cluster unitization. For example, databases and tables are sharded according to the unique coding information of the head office and branches. This coding information can be the organization's customer number. Based on the last three digits of the organization's customer number, the data can be split into 100 databases from 00 to 99. The last digit is used as the shard number. The server cluster is then divided into 10 units, each processing data from 10 distributed databases to improve data processing speed. That is, unit R00 needs to process distributed databases numbered 00-09.

[0057] However, the above approach may have the following issues: a head office may have multiple associated branches, but the head office's coding information differs from that of the branches. Taking the organization's customer number as an example, if the last three digits of the head office's customer number are not identical to the last three digits of the branch's customer number, then the head office and branches will be split into different units. For instance, if the head office located in unit R00 has updated information, such as updated contact information, the corresponding branch needs to synchronously update the head office's contact information. The branch might be located in unit R00, unit R03, unit R06, or other units. Due to the loose coupling requirement of the unit-based architecture, different units can only make service calls and cannot directly access the distributed database. This means that the distributed database information of unit R03 cannot be obtained from unit R00, and therefore the distributed database of the branch cannot be directly accessed, i.e., update operations cannot be performed.

[0058] Since the head office and branch offices are not in the same unit, to achieve synchronized updates of information between the head office and branch offices, unitized text can be generated based on the relationship between the head office and branch office structures and the updated information of the head office. In one possible implementation, multiple unitized texts are stored in a preset path, which can be Network Attached Storage (NAS), to facilitate the merging of unitized texts. The merged data file is then stored, and the data file is processed line by line through service calls.

[0059] On a given date, if existing transactions need to be modified, all transactions involving changes to the head office must be recorded in update details. After the head office completes the information update, the updated information will be recorded in an update details table. The update details table records the head office's update details data, and its structure includes: the name of the target table to be modified, the primary key of the target table to be modified, and the record after the change. Head office code information and branch office update information can be obtained from this update details table.

[0060] After the change, the records are separated by a specific delimiter and have different formats according to different business types, as illustrated below.

[0061] 1. Personnel Relationship Table: Relationship / Role | Relationship Person's Customer Number | Legal Entity Code | ... | Latest Modified Teller Number | Modified Teller Organization Number.

[0062] 2. Shareholder Information Table: Shareholder Customer Number | Legal Entity Code | Shareholder Type Code | ... | Create Teller Institution Number | Latest Modified Teller Number | Modified Teller Institution Number.

[0063] Based on the above, if the head office has updated information, the information of all branches under the head office can be obtained through the relationship table, and the specific content of this update can be obtained through the update details table. Using the relationships and update information, unitized text is generated. The unitized text can include branch update information (update information corresponding to branches in the head office update information). This branch update information can include branch update data and branch code information. Specifically, the branch update data includes the information fields where the branch has changed and the change details of the branch information fields. Each branch corresponding to the head office is located based on the relationships; the branch update information generated here is the update information corresponding to all branches.

[0064] It should be noted that when initially implementing distributed data storage, the relationship between the financial institution's headquarters and branches can be pre-stored using a relationship table. This table can be used to retrieve the relationships between the head office and branches. This relationship table stores business fields such as the head office customer number, branch customer number, head office organization number, due diligence process type code for branch customer numbers, and city code for branch customer numbers. Transactions involving modifications to the head office organization number, due diligence process type code, or city code require updating the reverse relationship in the relationship table, meaning all branches under the head office need their information updated. The aforementioned relationship table and update detail table must be maintained.

[0065] S102: Merge the unitized text to obtain a data file.

[0066] S103: Process the data file line by line to obtain the target branch office update information.

[0067] If multiple headquarters change their information on the same date, and these headquarters may be distributed across different units, resulting in 10 unitized files generated from 10 units, this application embodiment uses a text merging method, requiring two service calls: text merging and line-by-line text processing. Without merging the text, 10 file splitting service calls would be needed, processing 10 separate files. The steps of merging the unitized text to obtain a data file, and then performing line-by-line analysis of the data file's content, reduce the frequency of service calls, reduce the number of small files on the server, and improve the efficiency of information synchronization and updates.

[0068] In one possible implementation, processing the data file line by line to obtain the target branch office update information includes: processing the data file line by line according to the database sharding and table partitioning rules to obtain the target branch office update information.

[0069] Specifically, based on the database sharding and table partitioning rules, the data in each row of data is read and retrieved according to the last three digits of the branch organization code information in the data file. Then, the corresponding unit, distributed database and business table are located, and the corresponding field content of the business table is updated according to the data content retrieved row by row.

[0070] S104: Determine the target distributed database of the target branch based on the target branch update information.

[0071] In one possible implementation, the target branch office update information includes target branch office coding information, and determining the target distributed database of the target branch office based on the target branch office update information includes: determining the target distributed database of the target branch office based on the target branch office coding information.

[0072] The system maintains a relationship table between the head office and branches. The head office code information can be determined first, and then the branch customer number information corresponding to all the head offices can be obtained from the relationship table through the head office code information, such as the unique head office customer number.

[0073] In one possible implementation, determining the target distributed database of the target branch based on the target branch's coding information includes: determining the target business table of the target branch based on the target branch's coding information, the target business table being stored in the target distributed database; the target branch update information further includes target branch update data; and synchronizing and updating the target distributed database based on the target branch update information includes: synchronizing and updating the target business table based on the target branch update data.

[0074] After obtaining the branch office customer number information (branch office code information), the database information of the branch office can be obtained according to the rules of database sharding and table partitioning, based on the last three digits of the customer number. The distributed database uses a distributed architecture to split the data into 10 units based on the last three digits of the branch office customer number, with each of the 10 units connecting to 10 databases, resulting in a total of 100 databases from 00 to 99. Business table sharding is based on distributed database sharding. The last three digits of the branch office's unique code are used to obtain the corresponding database from 00 to 99 (100 databases in total). The last digit is used as the shard number, corresponding to one of the 10 shards for each table in a single database. For example, if the last two digits are 123, the first two digits are 12, so the database is in unit R01 (unit R01 contains databases 10-19, and 123 is in database 12). The last digit of 123 is 3, so the record is in the third shard of the business table, for example: t_basic_info_123 shard. By using the last digit of the branch number, one can locate the unit, database, and specific business table shard where the branch information is located.

[0075] S105: Based on the updated information of the target branch, perform information synchronization and update of the target distributed database.

[0076] The data file is processed line by line, parsing each line to obtain the target branch office update information. This update information includes the target branch office code and the target branch office update data. Based on the code, the target business table for the target branch office is determined, and this table is stored in the target distributed database. The update data includes the fields that need to be updated, details of the updated fields, etc. Based on this update data, the target business table is synchronously updated.

[0077] In one possible implementation, the method further includes: obtaining the information synchronization update result; if the information synchronization update result indicates that the information synchronization update has failed, generating a prompt message. Based on the prompt message, the reason for the update failure is determined, and then the update is performed again to ensure that the information synchronization update can be completed.

[0078] Based on the above, we know that the code information of all branches under the head office with updated information is determined from the relationship table between the head office and branches. The head office code information can also be used to query the head office update information from the update details table. Combining the relationship table and the update details table, we obtain the data to be processed: branch office update information, which is obtained based on the relationship table and the head office update information. The data to be processed is written to the unit's file, and the data from 10 units is merged into one data file. The data file content is read line by line and processed. When a line of data is read, it contains the head office code information, branch office code information, and head office update information. The branch office code information can be used to locate the database and business table shard where the branch office is located, and then the corresponding column values ​​of the branch office are updated according to the head office update information. It's important to clarify that data file sharding doesn't mean splitting the entire data file; rather, it involves extracting a single record. Based on the unique identifier within each record, the unit containing that information is determined. Then, through microservice calls across distributed units, the retrieved record is passed as a request parameter to the target unit where the branch office is located. The target unit then uses the branch office's coding information to locate the specific database and business table for information synchronization. This process continues reading the data file until all rows have been processed. By maintaining historical processing records during data processing and leveraging distributed database sharding rules to process the data file containing update information from all branches line by line to obtain the target branch's update information, and then determining the branch's database based on that information for synchronization, reliability is ensured. The information synchronization operation is simple, fast, and efficient.
