Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, apparatus, terminal and storage medium for data synchronization. Background Technology

[0002] In anti-fraud operations, algorithmic data such as rules / models are a crucial part of the fraud cleansing process. In many cases, this algorithmic data needs to be deployed as a service for downstream businesses to access at any time, thus meeting certain real-time requirements. To ensure service stability during deployment, at least two terminals are deployed simultaneously to provide a fault tolerance mechanism that allows the service to continue operating even if one terminal fails. However, this fault tolerance mechanism can lead to a situation where, when algorithmic data is updated, only one terminal updates the data, while other terminals retain the old algorithmic data. This can result in downstream businesses potentially still using the old algorithmic data when making requests, impacting business implementation.

[0003] Currently, many platforms use restarting to synchronize algorithm data in terminals. However, this method wastes resources and takes a long time to synchronize. If a subscription method is used, it relies too much on external services. If the external services have problems, it is easy to cause data synchronization failure and reduce service stability. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] To facilitate understanding of the embodiments of the present invention, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of the present invention.

[0041] The data synchronization method provided in this embodiment of the invention will be described in detail below. The data synchronization system includes, for example... Figure 1 The diagram illustrates an example of an application scenario for a data synchronization method. The data synchronization system includes multiple data synchronization terminals 100 and a data development terminal 101 connected to each data synchronization terminal 100; wherein, Figure 1 Taking three data synchronization terminals 100 as an example, the specific number of data synchronization terminals 100 can be set according to actual needs and is not limited here.

[0042] The following section will detail a data synchronization method using the scenario structure diagram. (See also...) Figure 2 This is a flowchart illustrating an embodiment of a data synchronization method provided by the present invention. Figure 2 As shown, the process may include the following steps:

[0043] S201, any target data synchronization terminal among multiple data synchronization terminals receives a data operation instruction sent by the data development terminal, parses the data operation instruction, obtains the data operation information carried in the data operation instruction, and uploads the data operation information to the operation behavior data table;

[0044] A data development terminal can be understood as a terminal device that can operate on the data on a data synchronization terminal. When it is necessary to operate on the data on the data synchronization terminal, the data development terminal issues a data operation instruction. This data operation instruction will be randomly assigned to any one of the multiple data synchronization terminals, i.e., the target synchronization terminal. After receiving the data operation instruction, the target synchronization terminal needs to parse the data operation instruction to obtain the data operation information carried by the data operation instruction, and send the data operation information to the operation behavior data table for storage.

[0045] Among them, data operation information refers to specific information that enables operations on the data on the data synchronization terminal. This data is not limited to rule algorithm data, model algorithm data, or other application data that can realize business services.

[0046] The operation behavior data table is a data storage device that supports data access and data storage for all data synchronization terminals.

[0047] S202, each data synchronization terminal periodically polls to obtain data operation information from the operation behavior data table according to the first preset polling time, and performs data operations based on the data operation information to achieve data synchronization.

[0048] Multiple data synchronization terminals poll the operation behavior data table at regular intervals according to a first preset polling time. This allows them to obtain the data operation information uploaded to the operation behavior data table by the target data synchronization terminal. Each data synchronization terminal performs data operations based on the same obtained data operation information, thus synchronizing the data operations of all data synchronization terminals. This ensures the consistency of data in each data synchronization terminal and effectively improves service stability. The first preset polling time can be set according to actual needs and is not limited here.

[0049] by Figure 1 Taking the three data synchronization terminals shown as an example, if the first preset polling time is 10 seconds, the order from left to right is as follows: after the middle data synchronization terminal 100 uploads the data operation information to the operation behavior data table, the leftmost data synchronization terminal 100 accesses the operation behavior data table for the first time to obtain the data operation information. After a 10-second interval, the middle data synchronization terminal 100 accesses the operation behavior data table to obtain the data operation information, and after a 10-second interval, the rightmost data synchronization terminal 100 accesses the operation behavior data table to obtain the data operation information. When all data synchronization terminals obtain the same data operation information, each data synchronization terminal performs data operations based on the data operation information. Alternatively, each data synchronization terminal may start performing data operations based on the data operation information after obtaining it, without any limitation here.

[0050] This invention provides a data synchronization method, comprising: any target data synchronization terminal among multiple data synchronization terminals receiving a data operation instruction sent by a data development terminal; parsing the data operation instruction to obtain data operation information carried in the instruction; and uploading the data operation information to an operation behavior data table; each data synchronization terminal periodically polling the operation information in the operation behavior data table according to a first preset polling time, and performing data operations based on the operation information to achieve data synchronization. This invention randomly sends data operation instructions to a target data synchronization terminal, but all data synchronization terminals poll and jointly read the data operation information in the operation behavior data table. All data synchronization terminals perform data operations based on the operation information to complete data synchronization, ensuring data consistency across all data synchronization terminals. This method of achieving data synchronization without restarting or subscribing effectively reduces resource waste, long synchronization times, and unsuccessful data synchronization, greatly improving service stability.

[0051] In one implementation, if the data operation information includes a data update operation and a first data address corresponding to the data update operation, the data operation performed by each data synchronization terminal based on the data operation information in step 202 above can be achieved through steps A1 to A3:

[0052] Step A1: Download and obtain the updated data and the data identifier corresponding to the updated data based on the first data address;

[0053] The first data address is used to indicate the storage location of the updated data. That is, the file containing the updated data can be found through the first data address, and then the updated data can be obtained from the file containing the updated data.

[0054] The data identifier is a unique identifier for updated data, and can be represented by numbers, characters, letters or other forms, without limitation here.

[0055] Step A2: Obtain the data to be updated based on the data identifier;

[0056] Since the data synchronization terminal stores a large amount of data, each piece of data needs to be identified in order to clarify each piece of data. Using the data identifier of the updated data obtained in step A1, the data to be updated corresponding to the data identifier can be determined from the multiple pieces of data stored in the data synchronization terminal. This data to be updated is the data that needs to be updated in this data operation instruction.

[0057] Step A3: Replace the data to be updated with the updated data based on the data update operation.

[0058] The data synchronization terminal updates the data by replacing the data to be updated with the updated data.

[0059] In one implementation, if the data operation information includes a data deployment operation, and a service identifier and a deployment data identifier corresponding to the data deployment operation, the data operation performed by each data synchronization terminal based on the data operation information in step 202 above can be achieved through steps B1 to B2:

[0060] Step B1: Obtain deployment data based on the deployment data identifier;

[0061] Since the data synchronization terminal stores a large amount of data, each piece of data needs to be identified in order to distinguish each piece of data. By deploying data identifiers, the deployment data corresponding to the deployment data identifier can be determined from the multiple pieces of data stored in the data synchronization terminal. This deployment data is the data that provides data services to the service.

[0062] Step B2: Based on the data deployment operation, deploy the deployment data to the service corresponding to the service identifier.

[0063] The service identifier is a unique identifier for a service, which can clearly identify which specific service it is.

[0064] Deployment can be understood as the specific service to which deployment data is deployed for application. For example, migrating the vgg16 model in the source domain to the data monitoring service as a new scenario initialization model for data monitoring.

[0065] In one implementation, if the data operation information includes a data offline operation and an offline data identifier corresponding to the data offline operation, the data operation performed by each data synchronization terminal based on the data operation information in step 202 above can be achieved through steps C1 to C2:

[0066] Step C1: Obtain the data to be taken offline based on the offline data identifier;

[0067] Since the data synchronization terminal stores a large amount of data, each piece of data needs to be identified in order to distinguish each piece of data. The offline data identifier can be used to determine the data to be offline corresponding to the offline data identifier from the multiple data stored in the data synchronization terminal. The data to be offline is the data that needs to be offline in this data operation instruction.

[0068] Step C2: Based on the data offline operation, offline the data to be offline.

[0069] According to the data offline operation, the data to be offline is processed to achieve the data offline in the data synchronization terminal.

[0070] In practical use, data operations are not limited to data updates, data deployments, and data decommissioning. Specific data operations can also include data processing and other operations, which will be described in detail here.

[0071] See Figure 3 This is a flowchart illustrating an embodiment of another data synchronization method provided by the present invention. Figure 3 As shown, the process may include the following steps:

[0072] Step 301: Any target data synchronization terminal among multiple data synchronization terminals receives a data operation instruction sent by the data development terminal, parses the data operation instruction to obtain the data operation information carried in the data operation instruction, and uploads the data operation information to the operation behavior data table.

[0073] Step 301 above can be referred to step 201, and will not be repeated here.

[0074] Step 302: Each data synchronization terminal periodically polls to obtain data operation information from the operation behavior data table according to the first preset polling time, searches for the terminal operation status that matches the terminal identifier corresponding to the data synchronization terminal in the terminal information table, updates the terminal operation status to the first terminal operation status, and performs data operations based on the data operation information to achieve data synchronization.

[0075] The terminal information table stores the terminal identifiers of each data synchronization terminal, as well as the terminal operation status corresponding to each terminal identifier. Specifically, the target terminal identifier that matches the terminal identifier corresponding to the data synchronization terminal can be found in the terminal information table, and then the terminal operation status corresponding to the target terminal identifier can be determined as the terminal operation status corresponding to the data synchronization terminal.

[0076] The terminal operation status is used to characterize the current state of the data synchronization terminal's data operation. In this embodiment, the first terminal operation status is used to characterize the data synchronization terminal's incomplete data operation state, and the second terminal operation status is used to characterize the data synchronization terminal's completed data operation state.

[0077] Since the terminal operation status was the second terminal operation status after the last data operation command, in order to clarify the completion status of the current data operation command, it is necessary to first update the terminal operation status from the second terminal operation status to the first terminal operation status after the completion of the last data operation command. Then, after the completion of the current data operation command, the terminal operation status is updated from the first terminal operation status to the second terminal operation status to indicate the completion of the current data operation command.

[0078] Step 303: For each data synchronization terminal, when the data operation is detected to be completed, update the terminal operation status corresponding to the data synchronization terminal to the second terminal operation status.

[0079] Step 304: Each data synchronization terminal polls the terminal information table periodically according to the second preset polling time. When it is detected that all terminal operation statuses in the terminal information table are in the second terminal operation status, each data synchronization terminal deletes the operation record of the data operation, and the target data synchronization terminal deletes the data operation information in the operation behavior data table.

[0080] In actual use, the data operation process performed by the data synchronization terminal based on the data operation information is stored locally in the form of operation records. In order to save storage space in the data synchronization terminal, each data synchronization terminal polls the terminal information table at regular intervals according to the second preset polling time. When it is determined that the operation status of all terminals is the second terminal operation status, that is, all data synchronization terminals have completed the data operation of this data operation instruction, the operation record corresponding to this data operation stored locally is deleted.

[0081] In this embodiment, when each data synchronization terminal determines that all terminal operation states are in the second terminal operation state, the target data synchronization terminal deletes the data operation information in the operation behavior data table to ensure that the same data operation is only executed once, thus avoiding the data synchronization time delay caused by the data synchronization terminal performing the same data operation multiple times.

[0082] See Figure 4 This is a block diagram of an embodiment of an application generation device provided by the present invention. The device is suitable for a data synchronization system, which includes multiple data synchronization terminals and a data development terminal connected to each data synchronization terminal. The device includes:

[0083] The parsing and uploading module 401 is used to receive data operation instructions sent by the data development terminal from any target data synchronization terminal among multiple data synchronization terminals, parse the data operation instructions, obtain the data operation information carried in the data operation instructions, and upload the data operation information to the operation behavior data table;

[0084] The data operation synchronization module 402 is used for each data synchronization terminal to periodically poll and obtain data operation information from the operation behavior data table according to a first preset polling time, and to perform data operations based on the data operation information to achieve data synchronization.

[0085] This invention provides a data synchronization device, comprising: any target data synchronization terminal among multiple data synchronization terminals receiving a data operation instruction sent by a data development terminal; parsing the data operation instruction to obtain data operation information carried in the instruction; and uploading the data operation information to an operation behavior data table; each data synchronization terminal periodically polling the operation information in the operation behavior data table according to a first preset polling time, and performing data operations based on the operation information to achieve data synchronization. This invention randomly sends data operation instructions to a target data synchronization terminal, but all data synchronization terminals poll and jointly read the data operation information in the operation behavior data table. All data synchronization terminals perform data operations based on the operation information to complete data synchronization, ensuring data consistency across all data synchronization terminals. This method of achieving data synchronization without restarting or subscribing effectively reduces problems such as wasted resources, long synchronization times, and unsuccessful data synchronization, greatly improving service stability.

Each of the data synchronization terminals polls the terminal information table periodically according to a second preset polling time. When it is detected that all the terminal operation states in the terminal information table are in the second terminal operation state, each of the data synchronization terminals deletes the operation record of the data operation, and the target data synchronization terminal deletes the data operation information in the operation behavior data table.

6. A terminal, characterized in that, include: A processor and a memory, the processor being configured to execute a data synchronization program stored in the memory to implement the data synchronization method according to any one of claims 1 to 4.

7. A storage medium, characterized in that, The storage medium stores one or more programs, which can be executed by one or more processors to implement the data synchronization method according to any one of claims 1 to 4.
