Description

Technical Field

[0001] The present invention relates to the technical field of data synchronization, and in particular to a multi-node CMDB block-based refined data synchronization method and system. Background Art

[0002] The Configuration Management Database (CMDB) is a logical database that contains information about the entire life cycle of configuration items and the relationships between configuration items (including physical relationships, real-time communication relationships, non-real-time communication relationships, and dependency relationships).

[0003] Multi-node CMDB refers to an architectural design that distributes storage and processing of CMDB data through multiple physical or logical nodes. This design can improve the availability, scalability and performance of the system. Each node can be responsible for a specific data shard or area, thereby achieving more sophisticated data management and faster data access speed.

[0004] However, in a multi-node environment, maintaining data consistency between nodes is a huge challenge. Since different nodes may read and write the same data at the same time, an efficient data synchronization mechanism is required to ensure that the data on all nodes remains up-to-date and consistent. There are two main types of data synchronization mechanisms: full synchronization and incremental synchronization:

[0005] 1. Full synchronization: This is the simplest and most direct way, that is, to regularly copy all data from the master node to other nodes. Although this method is easy to implement, it is inefficient, especially when the amount of data is large, it will occupy a lot of bandwidth and may cause a long period of data unavailability.

[0006] 2. Incremental synchronization: Compared with full synchronization, incremental synchronization only transmits data that has changed since the last synchronization. This greatly reduces the amount of data transmitted and improves synchronization efficiency. However, it requires a reliable change detection mechanism, and in some cases (such as retrying after partial failure), additional logic may be required to ensure eventual consistency.

[0007] The current existing data synchronization method mainly includes the following steps and processes:

[0008] 1. A CMDB (such as platform A) exposes a specific port (such as port 60010) and defines the corresponding API path, so that other systems can access the services provided by platform A;

[0009] 2. Another CMDB (such as Platform B) sets up synchronization configuration, configures how to connect to Platform A, and saves this configuration information in its own database;

[0010] 3. Platform B initiates HTTP requests or uses other protocols to pull all data from Platform A synchronously and store the data in the local database;

[0011] 4. Platform B regularly performs incremental synchronization, pulling only the data that has changed since the last synchronization, and incremental synchronization is pulled to the database at a fixed time.

[0012] However, existing data synchronization methods, especially the above-mentioned process of setting up a CMDB (such as platform A) to expose a specific port (such as port 60010) and allowing another CMDB (such as platform B) to obtain data through the specific port, do have some obvious limitations and challenges. The existing data synchronization methods mentioned above mainly have the following shortcomings:

[0013] 1. High complexity of API calls:

[0014] Users must have an in-depth understanding of the specific details of the API interface, including parameter configuration, error handling mechanism, etc. This increases development and maintenance costs, especially for non-technical personnel, it may be very difficult to understand and correctly use these APIs.

[0015] 2. Cross-domain network configuration is complex:

[0016] When it comes to cross-domain operations, network configuration becomes extremely complex. Not only does it need to ensure network connectivity between the two platforms, but it also needs to consider factors such as firewall rules and security policies. In addition, traffic control in different network environments is also a major challenge, which may lead to performance bottlenecks or security risks. Summary of the invention

[0017] In view of this, the purpose of the present invention is to propose a multi-node CMDB block-based refined data synchronization method and system, introduce a synchronization channel mechanism, enhance data consistency, ensure that CMDB data between different areas is always up-to-date and consistent, and reduce management risks caused by data asynchrony; simplify the operating process, reduce the difficulty for users to understand and use complex technical tools, and improve work efficiency; improve system reliability, increase network accessibility and pre-synchronization correction judgment and other functions, effectively prevent data synchronization failures caused by network failures or configuration errors, and enhance the overall stability of the system; optimize resource utilization, adopt an event-driven model and incremental update strategy, and only transmit necessary data changes, thereby saving bandwidth and computing resources and improving synchronization efficiency.

[0018] The present invention provides a multi-node CMDB block-by-block refined data synchronization method, comprising the following steps:

[0019] S1. CMDB configures a synchronization channel and sets a synchronization timer task; the synchronization channel configuration includes: specifying the source area T1 and the target area T2, configuring a new synchronization channel in the CMDB of the T2 area, selecting an appropriate synchronization type, and opening the synchronization channel to ensure that the synchronization channel can normally monitor data changes from the T1 area;

[0020] The setting of the synchronization timing task includes: setting one or more timing tasks in the T2 area according to business requirements, and the timing tasks will regularly trigger the data synchronization process associated with the configured synchronization channel; configuring the time interval and execution strategy parameters of the timing tasks to meet specific synchronization frequency requirements;

[0021] S2. Before each synchronization starts, determine whether the service port of the T1 area is connected and whether the service port of the T1 area is accessible to ensure stable network connection; if the detection fails, record the error log and send an alarm to the administrator; if the detection succeeds, enter step S3;

[0022] S3, obtain the latest synchronization channel configuration information from the T1 area through API calls to guide subsequent data conversion and processing;

[0023] S4. According to the synchronization channel configuration information obtained from the T1 area, a synchronization channel is formally established in the T2 area, and the synchronization channel is opened to receive data; once the synchronization channel is opened, it immediately enters the ready state, waiting for the scheduled task to trigger the actual data synchronization operation;

[0024] S5. In the T2 area, associate the scheduled task set in step S1 with the synchronization channel created in step S4, and start scheduled synchronization;

[0025] Specifically, the previously set scheduled tasks need to be associated with the created synchronization channel in order to enable scheduled synchronization;

[0026] Scheduled tasks can be triggered manually or automatically started according to a preset schedule without manual intervention;

[0027] S6. Each time a scheduled task is triggered, a series of correction judgments are first performed. If all correction items are verified to be successful, the synchronization process officially begins; if any correction item fails to be verified, the synchronization attempt is stopped and a detailed explanation of the reasons is recorded for subsequent analysis.

[0028] The present invention sets a correction judgment function before synchronization. When the user modifies the model field, the user can first perform correction after the modification is completed, and then manually pull the data and set the scheduled task.

[0029] Further, the synchronization type in the selection of the appropriate synchronization type in step S1 includes: full synchronization, incremental synchronization, and event-driven;

[0030] The full synchronization is to synchronize all the model instances in the T1 area to the corresponding model instances in the T2 area;

[0031] The incremental synchronization is to synchronize the model instance in the T1 area to the corresponding model instance in the T2 area according to the time period change;

[0032] The event-driven method is to synchronize the mirror instances of the model in the T1 area and the corresponding model in the T2 area. Changes in the model instance in the T1 area or the model instance in the T2 area will cause changes in the mirror instance, which will be synchronized to the other end area to maintain consistency.

[0033] The present invention introduces an incremental update mechanism to transmit only the changed data. At the same time, it combines an event-driven model to ensure rapid response to configuration changes, which can not only reduce bandwidth usage and synchronization time, but also achieve near real-time data synchronization, which is more efficient than the full synchronization method.

[0034] Furthermore, the method of associating the scheduled task set in step S1 with the synchronization channel created in step S4 in step S5 includes:

[0035] The ID number of the created synchronization channel and the configuration information of the synchronization channel are associated with the set scheduled tasks to ensure that each scheduled task can accurately act on the correct synchronization channel.

[0036] Furthermore, the synchronization channel configuration information in the step S3 of acquiring the latest synchronization channel configuration information from the T1 area includes: data mapping rules and filtering conditions.

[0037] Furthermore, the execution of a series of correction judgments in step S6 includes: verifying the validity of the source data, and the method of verifying the validity of the source data includes: obtaining corresponding data by calling the API path corresponding to the service port of the T1 area during each synchronization, parsing the data, and determining whether the data is valid.

[0038] The present invention also provides a multi-node CMDB block-based refined data synchronization system, which is used to implement the multi-node CMDB block-based refined data synchronization method as described above, including:

[0039] Configuration of synchronization channel and scheduled task module: used for CMDB configuration of synchronization channel and setting of synchronization scheduled tasks; the configuration of synchronization channel includes: specifying source area T1 and target area T2, configuring a new synchronization channel in the CMDB of area T2, selecting an appropriate synchronization type, opening the synchronization channel, and ensuring that the synchronization channel can normally monitor data changes from area T1; the setting of synchronization scheduled tasks includes: setting one or more scheduled tasks in area T2 according to business needs, and the scheduled tasks will regularly trigger the data synchronization process associated with the configured synchronization channel; configuring the time interval and execution strategy parameters of the scheduled tasks to meet specific synchronization frequency requirements;

[0040] Network reachability detection module: used to determine whether the service port of the T1 area is connected before each synchronization starts, check whether the service port of the T1 area is accessible, and ensure the stability of the network connection; if the detection fails, the error log is recorded and an alarm is sent to the administrator; if the detection is successful, the S3 step is entered;

[0041] Synchronous configuration pull module: used to obtain the latest synchronous channel configuration information from the T1 area through API calls to guide subsequent data conversion and processing;

[0042] Creating a synchronization channel module: used to formally establish a synchronization channel in the T2 area according to the synchronization channel configuration information obtained from the T1 area, and open the synchronization channel to receive data; once the synchronization channel is opened, it immediately enters the ready state, waiting for the scheduled task to trigger the actual data synchronization operation;

[0043] Configure the associated scheduled task module: used to associate the scheduled task set in step S1 with the synchronization channel created in step S4 in the T2 area, and start scheduled synchronization;

[0044] Scheduled task correction judgment module: It is used to perform a series of correction judgments each time a scheduled task is triggered. If all correction items are verified, the synchronization process will officially start; if any correction item fails to be verified, the synchronization attempt will be stopped and a detailed explanation of the reason will be recorded for subsequent analysis.

[0045] The present invention can bring the following significant beneficial effects in practical applications by introducing a synchronous channel mechanism:

[0046] 1. Enhance data consistency:

[0047] Through the intelligent mapping engine and incremental update mechanism, the CMDB data between different regions is ensured to always remain up-to-date and consistent, reducing the management risks caused by data asynchrony.

[0048] 2. Simplify the operation process:

[0049] The use of visual workflow editors and advanced API encapsulation greatly reduces the difficulty for users to understand and use complex technical tools, thereby improving work efficiency.

[0050] 3. Improve system reliability:

[0051] The added functions of network reachability and pre-synchronization correction judgment can effectively prevent data synchronization failures caused by network failures or configuration errors, and enhance the overall stability of the system.

[0052] 4. Optimize resource utilization:

[0053] By adopting an event-driven model and incremental update strategy, only the necessary data changes are transmitted, which greatly saves bandwidth and computing resources and improves synchronization efficiency.

[0054] 5.Support flexible expansion:

[0055] Flexible mapping rules and synchronization strategies that support dynamic adjustment have been designed to quickly adapt to changes in business needs and technical environment, providing a good foundation for future system upgrades.

[0056] The present invention also provides a computer-readable storage medium having a computer program stored thereon, and when the program is executed by a processor, the steps of the multi-node CMDB block-based refined data synchronization method as described above are implemented.
