Problems solved by technology

[0003] First, data migration involves the interaction between production and test environments, requiring a change application, resulting in a long process
[0004] Second, the dump method is adopted in the traditional ORACLE database, and the client tool programs EXP and IMP are used
When dumping files, someone needs to pay attention to the dump process, find out and solve errors in time, and consume manpower; the exported files are stored in the scheduling server, which will occupy storage resources and affect the operation of other programs; the file transfer rate is low
[0005] Third, when performing data migration in a traditional distributed database, it is necessary to send import / export tasks from the data management node to the data node and receive the processing results. The task pressure on the management node is huge

Abstract

The embodiment of the invention provides a distributed cluster data migration method and device, relates to the field of big data processing and can also be used for the financial field, and the method comprises the following steps: performing data deformation on to-be-migrated data in a source database according to a preset data deformation rule, extracting the to-be-migrated data subjected to data deformation to a target table of the source database, wherein the target table is mapped to a corresponding transfer machine through a data transmission port and an IP address defined in a preset appearance; extracting data in the target table to the appearance, and generating a transfer machine data file, so that a scheduling server migrates the transfer machine data file to a corresponding target database according to directory parameters in the transfer machine; the data migration efficiency can be effectively improved, and system and human resources are saved.

Description

technical field [0001] This application relates to the field of distributed technology, and can also be used in the field of big data processing or finance, and specifically relates to a distributed cluster data migration method and device. Background technique [0002] Based on the background of big data distributed cluster data migration, the data migration scenario of large-scale data import / export currently has the following difficulties: [0003] First, data migration involves the interaction between the production and test environments, requiring a change application, resulting in a longer process. [0004] Second, the dump method is adopted in the traditional ORACLE database, and the client tool programs EXP and IMP are used. Based on production control requirements, the data needs to be deformed before exporting. The general process is "data deformation" → "dump export file" → "transfer" → "dump import file". When dumping files, someone needs to pay attention to t...
