Abstract

The invention relates to the technical field of big data, and discloses a data synchronization processing method, device and apparatus and a storage medium, which are used for improving data conversion and import efficiency. The data synchronization processing method comprises the following steps: reading a plurality of table structure data in batches from a preset distributed file system according to a data mining request; according to structured query language (SQL) grammar rules, sequentially performing data cleaning and statement splicing on the plurality of table structure data to obtaina plurality of SQL query statements; connecting the target relational database, and performing data query operation according to the plurality of SQL query statements to obtain a query result set; performing data cleaning and format conversion on the query result set to obtain a plurality of distributed file system files; and respectively importing the plurality of distributed file system files into a preset distributed file system to obtain an updating result, and sending the updating result to the target terminal. In addition, the invention also relates to a blockchain technology, and a plurality of table structure data can be stored in the blockchain node.

Description

technical field [0001] The present invention relates to the incremental synchronization field of big data technology, in particular to a data synchronization processing method, device, equipment and storage medium. Background technique [0002] As the application of big data becomes more and more widespread, it is often necessary to extract data from traditional relational databases (such as oracle or mysql), perform operations such as cleaning and assembling, and finally synchronize it to the data warehouse of the big data platform. [0003] However, the underlying database system HDFS in the existing commonly used big data platforms is very different from traditional relational databases. The data storage format and storage rules are completely different. Even with the help of existing synchronization tools, there are still problems with cumbersome conversion steps and difficult conversion. At the same time, when it comes to the conversion of massive data, there is also th...
