Embodiment Construction

[0023] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0024] figure 1 It is a schematic diagram of an implementation environment shown according to an exemplary embodiment. The implementation environment includes: a data collector 101 , a target database 102 , and a source database 103 to which the method for synchronizing data provided by the embodiments of the present disclosure is applied. Wherein, the data collector 101 and the target database 102 can be arranged on the server side. For example, the data collector 101 can grab source data from the source database 103 and synchronize the source data to the target database 102 . Wherein, the source data may be synchronized to the target database 102 after r...

Abstract

The invention provides a data synchronization method and device. The method comprises the steps of obtaining source data; matching the source data with target data in a cache, thereby obtaining a matching result of the source data, wherein the target data in the cache is pre-loaded to the cache from a target database; determining an database operation needing to be carried out on the source data according to the matching result; and submitting the database operation needing to be carried out on the source data to the target database for performance according to a preset condition. A purpose of improving the data synchronization performance greatly is realized.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a method and device for synchronizing data. Background technique [0002] In the field of data processing, after the source data of the source database is extracted and transformed, it needs to be synchronized to the target database. Before the source data is synchronized to the target database, it needs to be queried one by one in the target database. If the source data matches the existing records of the target data, the source data will be updated to the target database. If they do not match , to insert that source data into the target database. [0003] However, due to the low matching performance of the database, the efficiency of data synchronization is too low, which cannot meet the needs of massive data processing. Contents of the invention [0004] In view of this, the present disclosure provides a method and device for synchronizing data, so as to achiev...
