Embodiment Construction

[0039] The present invention provides a data synchronization method, the data synchronization method is applied to a data synchronization system, the data synchronization system includes a source server, a target server and a client, the client sends instructions to the server through the network, and the source server acts as a The sender of the synchronization data, the target server is the receiver of the synchronization data. Wherein, the client is also referred to as the client, and refers to a program that corresponds to the server and provides local services for the client. Clients can be installed on, but not limited to, various personal computers, laptops, smartphones, tablets and portable wearable devices. Both the source server and the target server can be server clusters.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of t...

Abstract

The invention discloses a data sending method, a data receiving method, corresponding devices, equipment and a storage medium. The data sending method comprises the following steps: sending data to aserver, the source server determines a table structure and a data volume of to-be-synchronized source data; determining a time window for transmitting the source data; splitting the table structure according to the time window, the table structure of the source data and the data volume; obtaining N source sub-tables and N unit data mapped to the source sub-tables; and then, sending a data synchronization request to a target server, and sending the split data to the target server in parallel in a time window; and after the target server receives the split data in parallel, mapping each piece ofunit data in the N pieces of unit data and the source attribute parameters to a partition table of the corresponding target table. According to the invention, the time length of data synchronizationbetween the source server and the target server is greatly shortened, so that a data synchronization task can be completed in a specified time window.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data sending method, a data receiving method, a data sending device, a data receiving device, computer equipment and a computer-readable storage medium. Background technique [0002] Currently in the era of big data, big data technology is one of the core technologies of the industrial Internet. For these purposes, it is often necessary to migrate data between different databases, for example, to migrate data from the ORACLE database to the HIVE database. [0003] In the current technology, due to the different data storage methods of the HIVE library and the ORACLE library, there are certain performance bottlenecks when data is synchronized. For example, in the current technology, the data in the ORACLE database can be directly fetched from The data is synchronized to the HIVE database, but the HIVE database needs to complete the data migration in the ORACLE databas...
