Technical Field

[0001] The present invention relates to the technical field of database synchronization, and in particular to a database synchronization method. Background Art

[0002] In recent years, with the explosion of information in the information age, database products have been widely used in various industries. Furthermore, with the increasing expansion of the Internet, various large-scale data services on the Internet need to deal with massive amounts of data and also need the support of database technology. In applications that require massive amounts of data, it is often necessary to maintain synchronization between multiple databases, so that multiple databases can be used to provide database services to the outside world at the same time, increase data throughput access, enhance data availability, and also deal with data loss caused by unpredictable factors, which is conducive to ensuring data reliability. The existing database synchronization solution has the problems of slow synchronization speed, poor real-time performance and stability when the data volume is large; therefore, it does not meet the existing needs. In this regard, we propose a database synchronization method. Summary of the invention

[0003] The purpose of the present invention is to provide a database synchronization method. By configuring the source database, the successful connection between the source database and the target database can be ensured. At the same time, the security of the source database and the target database can be guaranteed through security configuration. The partition synchronization scheme can partition the source database and configure synchronization rules for the partitions. The data of different partitions are handled by the corresponding partitions of the target database, so that large-scale data can be processed, and the database synchronization status is continuously monitored and optimized as needed. The efficiency and accuracy of database synchronization can be ensured, and the synchronization result can be verified after the synchronization is completed, so as to ensure that all data has been correctly synchronized to the target database, thereby solving the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a database synchronization method, comprising the following steps:

[0005] Determine the synchronization target: Before starting database synchronization, clearly define the source database and target database to be synchronized;

[0006] Establish database connection: configure the source database to ensure successful connection between the source database and the target database, and ensure the security of the source database and the target database through security configuration;

[0007] Select a synchronization scheme: Select a partition synchronization scheme to partition the source database and configure synchronization rules for the partitions;

[0008] Synchronization test: Perform a test before formal synchronization to ensure that data can be synchronized correctly and there is no loss or error;

[0009] Execute database synchronization: After completing the above steps, start synchronization by scheduling or real-time and according to the configured synchronization rules;

[0010] Monitoring and optimization: Continuously monitor the database synchronization status, optimize as needed to ensure the efficiency and accuracy of database synchronization, and verify the synchronization results.

[0011] Furthermore, configure the connection information of the source database, including the database address, port, database name, account and password, to ensure correct connection to the source database and obtain the data to be synchronized. When the configuration is completed, establish a connection between the source database and the target database to achieve data synchronization between the source database and the target database.

[0012] Furthermore, the security of the source and target databases is ensured through security configuration, including using strong passwords, changing passwords regularly, limiting database access permissions, and log monitoring. Specifically:

[0013] Use strong passwords: Use strong passwords to increase the difficulty of cracking the source and target databases;

[0014] Change passwords regularly: Change passwords regularly to reduce the risk of password cracking;

[0015] Restrict database access permissions: By adjusting the access permissions of the source database and the target database, only authorized users can access the source database and the target database;

[0016] Log monitoring: Enable the log function of the source database and the target database and monitor them regularly. The log is used to record the access status of the source database and the target database. By analyzing the log, abnormal access behavior can be discovered in time.

[0017] Furthermore, the partition synchronization scheme includes the following steps:

[0018] Determine the partition basis and partition type: Before starting to partition the source database, determine the partition basis, which includes date and geographic location, and then select the corresponding partition type based on the partition basis;

[0019] Create a partition table: After determining the partition basis and partition type, create a partition table. When creating a partition table, use the partition keyword to specify the partition scheme and partition column to determine the partition table regulations. The partition regulations include the partition data type.

[0020] Data segmentation and storage: The data in the source database is segmented according to the partition type of the partition table, and the segmented data is stored in the corresponding partitions.

[0021] Furthermore, the partition and table structures in the source database and the target database are the same. If the partition and table structures in the source database and the target database are inconsistent, the target database is adjusted to ensure the consistency of the target database with the source database.

[0022] Furthermore, after the source database is partitioned, as the data changes, the partition data in the source database needs to be continuously updated and maintained, including adding new data, deleting obsolete data, and adjusting the partition structure.

[0023] Furthermore, before the formal synchronization, the synchronization process is tested to simulate the actual data changes in the source database. The test is used to check whether the corresponding changes in the target database are correctly synchronized. The synchronization task is then started after the test passes.

[0024] Furthermore, the test operation includes:

[0034] Connection monitoring: used to monitor the current number of connections, maximum number of connections, number of idle connections, number of active connections, and connection waiting time, so as to monitor the connection status between the source database and the target database in real time;

[0035] Resource monitoring: used to monitor CPU and memory usage, as well as disk I / O performance, to ensure the proper allocation and use of hardware resources during database synchronization;

[0036] Performance monitoring: used for query performance, including query execution time, query response time, query pass rate, and query execution times.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. Before starting database synchronization, the present invention clearly identifies the source database and the target database to be synchronized, and then configures the source database to ensure successful connection between the source database and the target database. Through security configuration, the security of the database connection can be effectively improved to reduce the risk of data leakage and illegal access. The database synchronization adopts a partition synchronization scheme. The partition synchronization scheme is to partition the source database and configure synchronization rules for the partitions. The partitions of the target database are consistent with the source database, and the data of different partitions are handled by the corresponding partitions of the target database, so that the target database can independently process the partitions it is responsible for. Through the partition synchronization scheme, when the data volume is large, large-scale data can be processed, thereby improving the synchronization speed.

[0039] 2. The present invention can understand the database synchronization status by continuously performing connection monitoring, resource monitoring and performance monitoring on the synchronization process, so that it can be optimized as needed to ensure the efficiency and accuracy of database synchronization. After the synchronization is completed, the synchronization result needs to be verified. By checking the consistency, completeness and accuracy of the data, it can be ensured that all data has been correctly synchronized to the target database. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 The flowchart of the database synchronization method of the present invention is shown in FIG. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In order to solve the technical problems of slow synchronization, poor real-time performance and stability in the existing database synchronization solution when the data volume is large, please refer to Figure 1 , this embodiment provides the following technical solutions:

[0043] A database synchronization method comprises the following steps:

[0044] Determine the synchronization target: Before starting database synchronization, clearly define the source database and target database to ensure that the database synchronization is carried out correctly;

[0045] Establish database connection: configure the source database to ensure successful connection between the source database and the target database for data transmission, and ensure the security of the source database and the target database through security configuration;

[0046] Select a synchronization scheme: Select a partition synchronization scheme to partition the source database and configure synchronization rules for the partitions. Select an appropriate synchronization scheme to meet the database synchronization requirements.

[0047] Synchronization test: Performing a test before formal synchronization can help identify and resolve problems that may arise during the synchronization process, ensuring that the actual synchronization is carried out smoothly, thereby ensuring that data can be synchronized correctly without loss or error;

[0048] Execute database synchronization: After completing the above steps, you can directly perform the actual database synchronization operation, and start synchronization through scheduled or real-time and according to the configured synchronization rules;

[0049] Monitoring and optimization: During the synchronization process, you need to pay close attention to the status of synchronization. Therefore, you need to continuously monitor the database synchronization status and optimize it as needed to promptly discover and resolve possible problems, ensure the efficiency and accuracy of database synchronization, and verify the synchronization results.

[0050] Configure the connection information of the source database, including the database address, port, database name, account, and password, to ensure that you can correctly connect to the source database and obtain the data that needs to be synchronized. When the configuration is complete, establish a connection between the source database and the target database to achieve data synchronization between the source database and the target database.

[0051] The technical effect of the above content is: after clarifying the source database and target database to be synchronized, the source database is configured, including configuring the database address, port, database name, account and password. By configuring the connection information of the source database, it is possible to ensure correct connection to the source database, avoid data synchronization errors between the source database and the target database, and thereby obtain the data that needs to be synchronized. When the connection between the source database and the target database is established, data synchronization between the source database and the target database can be achieved. By configuring the database connection as above, the reliability, availability, performance and data consistency of the database can be improved, thereby ensuring the integrity of data synchronization.

[0052] Ensure the security of the source and target databases through security configuration, including using strong passwords, changing passwords regularly, limiting database access permissions, and log monitoring. Specifically:

[0053] Use strong passwords: Use strong passwords to increase the difficulty of cracking the source and target databases;

[0054] Change passwords regularly: Change passwords regularly to reduce the risk of password cracking;

[0055] Restrict database access permissions: By adjusting the access permissions of the source database and the target database, only authorized users can access the source database and the target database;

[0056] Log monitoring: Enable the log function of the source database and the target database and monitor them regularly. The log is used to record the access status of the source database and the target database. By analyzing the log, abnormal access behavior can be discovered in time.

[0057] The technical effect of the above content is: through security configuration, the security of the source database and the target database can be improved. By using strong passwords, the difficulty of cracking the source database and the target database can be increased. The password should be complex and difficult to guess, containing letters, numbers and special characters, and be long enough. A strong password can greatly increase the difficulty of cracking, thereby reducing the chance of being attempted to crack by malicious attackers. By regularly changing passwords, the risk of password cracking can be reduced. If the password is changed frequently, the attacker needs to constantly update the cracking strategy, thereby increasing the difficulty of cracking. By adjusting the access rights of the source database and the target database, it can be restricted to only authorized users to access the database, thereby avoiding illegal access. By enabling the log function of the source database and the target database and performing regular monitoring, the access status of the source database and the target database can be mastered, so that the log can be analyzed, and abnormal access behavior can be discovered in time, and corresponding countermeasures can be taken. Through the real-time above-mentioned security configuration measures, the security of the database connection can be effectively improved and the risk of data leakage and illegal access can be reduced.

[0058] The partition synchronization scheme includes the following steps:

[0059] Determine the partition basis and partition type: Before starting to partition the source database, determine the partition basis, which includes date and geographic location, and then select the corresponding partition type based on the partition basis;

[0060] Create a partition table: After determining the partition basis and partition type, create a partition table. When creating a partition table, use the partition keyword to specify the partition scheme and partition column to determine the partition table regulations. The partition regulations include the partition data type.

[0061] Data segmentation and storage: The data in the source database is segmented according to the partition type of the partition table, and the segmented data is stored in the corresponding partitions.

[0062] The partition and table structures of the source database and the target database are the same. If the partition and table structures of the source database and the target database are inconsistent, the target database is adjusted to ensure the consistency of the target database with the source database.

[0063] The technical effect of the above content is: before starting partitioning, you first need to determine the partitioning basis. The partitioning basis can be date or geographic location. According to different partitioning bases, you can select the partitioning type, including range partitioning or list partitioning. Range partitioning is based on range division, such as date range, and list partitioning is based on column values, such as geographic location. After determining the partitioning basis and partitioning type, you can create a partition table. When creating a table, you need to use the partitioning keyword to specify the partitioning scheme and partitioning column, so that you can determine the data type of the partition, and then divide the data in the source database according to the partitioning type of the partition table, and store the divided data in the corresponding partition. The partition and table structure in the source database and the target database are the same, and the data of different partitions are handled by the corresponding partition of the target database. For example: the data of partition 1 in the source database is synchronized to partition 1 in the target database, so that the target database can independently process the partition it is responsible for. Through the above partition synchronization scheme, large-scale data can be processed when the data volume is large, thereby improving the synchronization speed and ensuring the real-time and stability of database synchronization.

[0064] After the source database is partitioned, as the data changes, the partition data in the source database needs to be continuously updated and maintained, including adding new data, deleting obsolete data, and adjusting the partition structure.

[0065] The technical effect of the above content is: as the data changes, the partition data in the source database needs to be continuously updated and maintained to ensure the integrity and continuity of the partition data. When new data needs to be added to the partition table, it can be inserted into the corresponding partition according to the specific attributes of the data (such as date or geographic location). For example, if the table is partitioned by date range, it can be inserted into the correct partition according to the CREATE_T I ME field value of the data. If the data meets the conditions of a partition, the data will be stored in the partition; if obsolete data needs to be deleted, the records of the corresponding partition can be directly deleted. When deleting data, only the partition where the deleted data is located will be affected, and the data of other partitions will not be affected. Obsolete data can be deleted by deleting a specific partition. For example, if a partition stores data before 2022, the partition can be directly deleted to remove the data; if the partition structure needs to be adjusted, such as merging partitions or re-dividing partitions, the ALTER TABLE statement can be used to add new partitions, merge partitions, or delete unnecessary partitions. The above operations can be flexibly adjusted according to the actual needs of the source database and data usage.

[0066] Before formal synchronization, test the synchronization process to simulate the actual data changes in the source database. Check whether the corresponding changes in the target database are synchronized correctly through testing. Start the synchronization task after the test passes.

[0067] Test operations, including:

[0068] Insert data: used to add new records to the source database;

[0069] Update data: used to modify existing data in the source database;

[0070] Delete data: used to remove records from the source database.

[0071] The technical effect of the above content is: before the actual synchronization, it is very necessary to conduct a simulated synchronization test. The test operations include inserting data, updating data, and deleting data. The test can help discover and solve problems that may arise during the synchronization process, and ensure the smooth progress of the formal synchronization. By simulating the actual data changes in the source database, you can check whether the corresponding changes in the target database are correctly synchronized. After the test passes, start the synchronization task. Through the above process, the test synchronization process verifies the accuracy and completeness of the data transmitted from the source database to the target database to ensure the correct operation of the database synchronization and ensure that the data is transmitted correctly between the source database and the target database. In addition, the test synchronization process can also help diagnose and solve problems that may arise during the synchronization process. It can determine whether the source database is synchronized with the target database, thereby diagnosing time synchronization problems. If the time is found to be out of sync, the test process can provide solutions, such as changing the time synchronization settings or checking network delay issues.

[0072] Monitoring and optimization, including the following steps:

[0073] Continuously monitor the synchronization process;

[0074] Improve synchronization efficiency and stability by monitoring and adjusting synchronization strategies or optimizing synchronization processes;

[0075] After the synchronization is completed, verify the synchronization results;

[0076] Verifying the synchronization results includes checking the consistency, completeness, and accuracy of the data to ensure that all data has been correctly synchronized to the target database.

[0077] Among them, the synchronization process is continuously monitored, including:

[0078] Connection monitoring: used to monitor the current number of connections, maximum number of connections, number of idle connections, number of active connections, and connection waiting time, so as to monitor the connection status between the source database and the target database in real time;

[0079] Resource monitoring: used to monitor CPU and memory usage, as well as disk I / O performance, to ensure the proper allocation and use of hardware resources during database synchronization;

[0080] Performance monitoring: used for query performance, including query execution time, query response time, query pass rate, and query execution times.

[0081] The technical effect of the above content is: after the synchronization solution is actually deployed, it is necessary to continuously monitor the synchronization process to ensure the real-time and consistency of the data. Through connection monitoring, the current number of connections, the maximum number of connections, the number of idle connections, the number of active connections, and the connection waiting time can be monitored. These indicators can help identify whether there are connection problems and avoid too many connections or too long connection waiting time. Through resource monitoring, the usage of resources such as CPU, memory, disk, and the load of the database server can be monitored to ensure that resources are used reasonably. Through performance monitoring, indicators such as query execution time, number of queries, slow query rate, and index efficiency can be monitored to identify performance bottlenecks and optimization opportunities. Through the above measures, the database synchronization process can be effectively monitored and optimized to ensure the stability and performance of database synchronization. After the synchronization is completed, the synchronization results need to be verified. By verifying the synchronization results, it can be ensured that all data has been correctly synchronized to the target database.

[0082] Working principle: After clearly defining the source database and target database to be synchronized, configure the source database to ensure successful connection between the source database and the target database, thereby improving the reliability, availability, performance and data consistency of the database and ensuring the integrity of data synchronization. At the same time, by using strong passwords, changing passwords regularly, limiting database access permissions and log monitoring and other security configurations, the security of database connections can be effectively improved, and the risk of data leakage and illegal access can be reduced. Database synchronization adopts a partition synchronization solution, which is to partition the source database and configure synchronization rules for the partitions. The partitions of the target database are consistent with the source database, and the data of different partitions are handled by the corresponding partitions of the target database. Processing allows the target database to independently process the partitions it is responsible for. Through the partition synchronization solution, when the data volume is large, it can process large-scale data, thereby improving the synchronization speed and ensuring the real-time and stability of database synchronization. Before the formal synchronization, the actual data changes in the source database are simulated to check whether the corresponding changes in the target database are correctly synchronized. After the test passes, the synchronization solution is actually deployed and the synchronization task is started. After the synchronization solution is actually deployed, the synchronization process needs to be continuously monitored. Through monitoring, the synchronization strategy can be adjusted or the synchronization process can be optimized to improve the efficiency and stability of synchronization. After the synchronization is completed, the synchronization result is verified to ensure that all data has been correctly synchronized to the target database by checking the consistency, completeness and accuracy of the data.

[0083] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
