Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data synchronization, in particular to a multi-node CMDB block refinement data synchronization method and system. BACKGROUND

[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 them, 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 CMDB data storage and processing across multiple physical or logical nodes. This design can improve system availability, scalability, and performance. Each node can be responsible for a specific data shard or region, enabling more refined data management and faster data access speeds.

[0004] However, maintaining data consistency across multiple nodes is a significant challenge. Since different nodes may simultaneously read and write to the same data, an efficient data synchronization mechanism is required to ensure that all nodes have the latest and consistent state of the data. Data synchronization mechanisms mainly include full synchronization and incremental synchronization:

[0005] 1. Full synchronization: This is the simplest and most direct method, which periodically replicates all data from the master node to other nodes. Although this method is easy to implement, it is inefficient, especially when the data volume is large, as it consumes a large amount of bandwidth and may result in a long period of data unavailability.

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

[0007] Current existing data synchronization methods mainly include 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, allowing other systems to access the services provided by platform A;

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

[0010] 3. B platform pulls data from A platform full synchronization by initiating HTTP requests or using other protocols, and stores data into local database;

[0011] 4. B platform performs incremental synchronization regularly, only pulling data changed since last synchronization, and incremental synchronization timing pulls to database.

[0012] However, the existing data synchronization method, especially the process of exposing a specific port (such as port 60010) of a CMDB (such as A platform) and allowing another CMDB (such as B platform) to obtain data through the specific port, indeed has some obvious limitations and challenges. The existing data synchronization method has the following disadvantages:

[0013] 1. High complexity of API calls:

[0014] Users must have a deep understanding of the specific details of API interfaces, including parameter configuration, error handling mechanisms, etc. This increases development and maintenance costs, and it can be very difficult for non-technical personnel to understand and correctly use these APIs.

[0015] 2. Complex cross-domain network configuration:

[0016] When cross-domain operations are involved, network configuration becomes exceptionally complex. Not only does it need to ensure network connectivity between the two platforms, but it also needs to consider firewall rules, security policies, and other factors. In addition, traffic control in different network environments is a major challenge, which can lead to performance bottlenecks or security risks. SUMMARY

[0017] In view of this, the purpose of the present application is to provide a multi-node CMDB block fine-grained data synchronization method and system, which introduces a synchronization channel mechanism, enhances data consistency, ensures that CMDB data between different regions always remains up-to-date and consistent, reduces management risks caused by data asynchronization, simplifies the operation process, reduces the difficulty of users to understand and use complex technical tools, improves work efficiency, improves system reliability, increases network accessibility and synchronization correction judgment functions, effectively prevents data synchronization failure problems caused by network failures or configuration errors, and enhances the overall stability of the system, optimizes resource utilization, uses an event-driven model and incremental update strategy, and only transmits necessary data changes, thereby saving bandwidth and computing resources and improving synchronization efficiency.

[0018] The present application provides a multi-node CMDB block fine-grained data synchronization method, comprising the following steps:

[0019] S1, a CMDB configuration synchronization channel is set, and a synchronization timing task is set; the configuration synchronization channel comprises: a specified source area T1 and a target area T2, a new synchronization channel is configured in the CMDB of the T2 area, a proper synchronization type is selected, and the synchronization channel is started to ensure that the synchronization channel can normally listen to data changes from the T1 area;

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

[0021] S2, before each synchronization starts, it is judged whether the service port of the T1 area is connected, it is checked whether the service port of the T1 area can be accessed, and the network connection is ensured to be stable; if the detection fails, an error log is recorded and an alarm is sent to the administrator; if the detection succeeds, the step S3 is entered;

[0022] S3, the latest synchronization channel configuration information is obtained from the T1 area through API calling, which is used to guide subsequent data conversion and processing work;

[0023] S4, according to the synchronization channel configuration information obtained from the T1 area, the synchronization channel is formally established in the T2 area, and the synchronization channel is started to receive data; once the synchronization channel is started, it enters a preparation state and waits for the timing task to trigger the actual data synchronization operation;

[0024] S5, the timing task set in the step S1 is associated with the created synchronization channel in the step S4, and the timing synchronization is started;

[0033] The application introduces an incremental update mechanism to only transmit changed data parts, and combines an event-driven model to ensure quick response to configuration changes, so that bandwidth occupation and synchronization time are reduced, near real-time data synchronization is realized, and the method is more efficient than the full synchronization method.

[0034] Further, the method of the S5 step of associating the created synchronization channel with the set timing task of the S1 step includes:

[0041] Synchronization configuration pulling module: used for acquiring the latest synchronization channel configuration information from T1 area through API calling, for guiding subsequent data conversion and processing work;
