Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The data transmission method provided by the application aims to solve the technical problems in the prior art.
The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
At present, the problem of data sharing from a bank data cloud platform to branch organizations such as branch local application systems is solved, and data interconnection and intercommunication among heterogeneous clusters are generally realized through a data synchronization technology. The method comprises the steps that a client is installed on one server, wherein the client is used for analyzing rule information of migration data, a local application system in a branch line submits the migration data to a migration scheduling server through the client, the migration scheduling server obtains the migration data and then puts the migration data into a queue, the migration data are distributed, then filtering conditions are pushed to a source cluster where the migration data are located to be fetched, and finally the data are transported to a target cluster.
However, the target cluster is generally a tenant space allocated to the local branch application system by the cluster of the head office application system on the data cloud platform, and the data is not in the database of the local branch application system.
Although the above solution can implement relocation of required data from the data cloud platform to the designated cluster, as described in the above solution, the cluster is generally a tenant space allocated to the local application systems of the branches by the cluster where the head office application system is located on the data cloud platform. Therefore, at this time, the data is still migrated in the cluster provided by the head office application system, the local branch application system can only perform data processing in the tenant space, and if the local branch application system has a demand for using the data in the local application system, the data needs to be exported to the local branch application system, so that the subsequent docking operation between the application system and the migrated data can be performed.
In addition, the branch local application system has more and more data scenes to use a data analysis tool provided by the head office application system to perform data processing work, and the back of the branch local application system needs to interface with branch tenants in the scheme. If the characteristic data of the local application system of the branch department needs to be processed by the head office tool, the local application system of the branch department is required to export the data of the local system, and the data is uploaded to the tenants of the data cloud platform of the head office application system through the interconnection tool.
Therefore, the two data relocation synchronization scenes have complicated steps and high technical cost, so that the technical cost of the local application system of the branch is high, and the data timeliness is poor.
