These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] Figure 1 This diagram illustrates an application scenario of a data synchronization method provided in this application. An example scenario is shown in the diagram: the source data obtained from the data source does not meet the user's usage scenario and cannot be used directly. The source data needs to be processed to obtain usable processed data, which is then stored in a database. The user can then retrieve the processed data from the database.

[0040] It should be noted that the data sources in this application include, but are not limited to, databases and applications.

[0041] The technical solutions of this application will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. In the description of this application, unless otherwise expressly specified and limited, the terms should be broadly understood within the art. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] Figure 2 This is a flowchart illustrating a data synchronization method provided in an embodiment of this application. The method includes the following steps:

[0043] S201. Based on the configuration file of the source data, the configuration file is parsed and processed to obtain configuration information.

[0044] As an example, the execution subject of this embodiment can be a data synchronization device, which can be implemented in various ways. For example, it can be program software, or a medium storing relevant computer programs, such as a USB flash drive; or, the device can also be a physical device that integrates or installs relevant computer programs, such as a chip, a smart terminal, a computer, a server, etc.

[0045] The configuration file includes information about the source data, such as data type, data size, and the corresponding task.

[0046] Optionally, data synchronization can be initiated by submitting a configuration file through the module to connect to the intelligent scheduling management system. The intelligent scheduling management system then creates an independently running container to perform data synchronization within that container.

[0047] Alternatively, the configuration file can be obtained from a file bound to the source data, or from the data source from which the source data originates.

[0048] S202. Based on the configuration information, determine the converter corresponding to the source data.

[0049] Among them, there are many types of source data. Based on the configuration information of different source data, the corresponding converter is determined.

[0050] Optionally, the types of transformations performed by the converter include, but are not limited to: data filtering, field filtering, function transformation, adjusting field order, and data reorganization.

[0051] S203. The source data is synchronized to the target database through the converter.

[0052] The converter processes the source data to obtain the target data, and includes a default implementation of preset conversion functions.

[0053] Optionally, this application supports user-defined converter functions, allowing users to customize the specific implementation of the conversion functions.

[0054] Alternatively, users can manage the data in the target database through a data management system.

[0055] It is understandable that a converter can adaptively transform the source data.

[0056] The data synchronization method provided in this application involves parsing the configuration file of the source data to obtain configuration information; determining the converter corresponding to the source data based on the configuration information; and synchronizing the source data to the target database through the converter. This solution, by determining the corresponding converter based on the configuration information of the source data, improves the adaptability of synchronized data compared to general protocols, as the corresponding converter can adapt to specific source data.

[0057] Based on any of the above embodiments, the following, in conjunction with Figure 3 The detailed process of data synchronization is explained.

[0058] Figure 3This is a flowchart illustrating a data synchronization method provided in an embodiment of this application. Figure 3 As shown, the method includes:

[0059] S301. Based on the configuration file of the source data, the configuration file is parsed and processed to obtain configuration information.

[0060] It should be noted that the execution process of S301 is the same as that of S201, and will not be repeated here.

[0061] S302. Determine the converter corresponding to the source data based on the configuration information.

[0062] One feasible implementation involves determining the converter corresponding to the source data based on the configuration information, including: obtaining the mapping relationship between the configuration information and the converter; and determining the converter corresponding to the source data through the configuration information and the mapping relationship.

[0063] In a scenario example, different converters are pre-configured based on different types of configuration information. Once the converters are configured, a mapping relationship between the configuration information and the converters is established. In a data synchronization scenario, the corresponding converter is determined by comparing the obtained configuration information with the mapping relationship.

[0064] S303. The source data is converted using the converter to obtain the target data.

[0065] In a scenario example, the converter performs transformation based on the field information of the source data and the table information of the database, thereby adapting the processed target data to the database.

[0066] It is understandable that the target data is compatible with the database, the database can correctly identify the target data, and the user can correctly call the target data.

[0067] S304. Obtain the read / write resource configuration input by the user.

[0068] In a specific scenario, read / write resource configuration includes configuring the ratio between read and write resources. In related technologies, the default ratio between read and write resources is set to 1:1. However, the different execution rates of reading and writing can lead to a long-tail effect, resulting in inefficient data synchronization.

[0069] For example, if the source data is read first and then written, and the ratio of read resources to write resources is set to 1:1 by default, there may be a situation where the previous batch of source data is being written while the next batch of source data has already completed its read task. This will cause the task of the next batch of source data to be suspended and thus affect the overall data synchronization efficiency.

[0070] It is understandable that the user-defined and reasonable read / write resource configuration in this application can avoid resource waste and improve the efficiency of data synchronization.

[0071] S305. Based on the read / write resource configuration, determine the ratio of read parallelism to write parallelism.

[0072] In a scenario example, read parallelism refers to the number of tasks that perform read operations simultaneously, while write parallelism refers to the number of tasks that perform write operations simultaneously.

[0073] Optionally, a conversion layer can be set to convert between read parallelism and write parallelism.

[0074] S306, Get the total number of pipes.

[0075] Optionally, the pipe level can be raised to the abstract level, and a memory pipe can be implemented using a Java queue model, with pipe file supplementation implemented using a Linux server.

[0076] In a scenario example, source data is retrieved from the data source and inserted into the database via pipelines. Each pipeline can process data in parallel. Pipelines can be configured by the user; since this application implements decoupling of read and write operations, pipelines can be configured according to the ratio of read parallelism to write parallelism.

[0077] S307. Synchronize the target data to the target database according to the read pipe and the write pipe.

[0078] Optionally, each piece of data can be set up as a task and executed via a pipeline.

[0079] Alternatively, tasks can be invoked through a scheduling module, which can enable the execution of the smallest possible task.

[0080] Below, in conjunction with Figure 4 Explain the operation of the pipeline.

[0081] Figure 4 This is a schematic diagram of pipeline operation provided for an embodiment of this application. Figure 4 As shown, each source data is established as a task, for example, the ratio of read pipeline to write pipeline is 3:2. Three tasks are obtained from the source data tasks for reading, and the read tasks are executed in parallel through the three read pipelines. After the read tasks are completed, a conversion layer is used to convert the pipeline between the read pipeline and the write pipeline, and the write tasks are executed in parallel through the two write pipelines. The ratio of read pipeline to write pipeline is determined based on the fact that the time consumed by the read task is the same as the time consumed by the write task, so as to avoid the tailing effect.

[0082] For example, when the previous batch of source data completes its read task and begins its write task, the next batch of source data begins its read task. Similarly, after the previous batch of source data completes its write task, the next batch of source data completes its read task.

[0083] A feasible implementation method for synchronizing target data to the target database based on the read pipeline and the write pipeline includes: obtaining the number of read pipelines and the number of write pipelines; sequentially obtaining the number of source data points of the number of read pipelines from the target data, sending the source data to the converter through the read pipelines, performing conversion processing on the source data through the converter to obtain the target data; and sequentially obtaining the number of target data points of the number of write pipelines from the converter, and synchronizing them to the target database through the write pipelines.

[0084] In a scenario example, during data synchronization, the number of read pipes and the number of write pipes are determined based on the ratio of read parallelism to write parallelism and the total number of pipes. The sum of the number of read pipes and the number of write pipes is less than or equal to the total number of pipes, and the ratio of the number of read pipes to the number of write pipes is equal to the ratio of read parallelism to write parallelism.

[0085] In this feasible implementation, data synchronization is performed according to the ratio of read parallelism to write parallelism, which can maximize resource utilization.

[0086] One feasible implementation method for data synchronization further includes: obtaining the data synchronization status of each source data through a monitor, wherein the data synchronization status includes synchronization success or synchronization failure; and sending the data synchronization status to the management system.

[0087] Below, in conjunction with Figure 5 Explain the monitor.

[0088] Figure 5 This is a schematic diagram of a monitor provided in an embodiment of this application. Figure 5 As shown, data synchronization from the data source to the target database is achieved through containers. The monitor obtains the data synchronization status from the container and sends the data synchronization status to the management system. Users can query the data in the target database or query the data synchronization status in the management system.

[0089] In a scenario example, users can locate the source data that failed to synchronize based on the synchronization status in the management system and resolve the corresponding fault.

[0090] In this feasible implementation, the monitoring system can promptly detect data that fails to synchronize, thereby addressing the root cause of the synchronization failure.

[0092] The parsing module 61 is used to parse the configuration file according to the configuration file of the source data to obtain configuration information.

[0093] The determining module 61 is used to determine the converter corresponding to the source data based on the configuration information.

[0094] The synchronization module 63 is used to synchronize the source data to the target database through the converter.

[0095] Optionally, the parsing module 61 can execute Figure 2 S201 in the embodiment.

[0096] Optionally, module 62 can be executed. Figure 2 S202 in the embodiment.

[0097] Optionally, synchronization module 63 can execute Figure 2 S203 in the embodiment.
