Abstract

The invention discloses a method and a device for migrating relational data to an HBase database, which are used for solving the technical problem that the data migration mode of migrating data from arelational database to an HBase database is not mature enough so as to improve the data migration efficiency, and can ensure integrity and effectiveness of data migration through a fault-tolerant verification mode so as to improve the accuracy of data migration. The method comprises: obtaining a data table needing to be migrated from a relational database; creating a column family name and a column name for a target HBase database according to the data table needing to be migrated; converting the field type into a character type to carry out data conversion on the data in the data table needing to be migrated to obtain converted data, and recording the converted data volume; importing the converted data into the target HBase database and generating an import record report; and judging theintegrity of data migration according to the converted data volume and the import record report so as to obtain a verification result about whether the data is completely migrated or not.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and device for migrating relational data to an HBase database. Background technique [0002] HBase is a sub-project of the Hadoop project. It is an implementation of a NOSQL database on Hadoop. It is also a distributed, column-oriented open source database. It can be said that HBase not only has the advantages of most NOSQL databases, but also has It is seamlessly integrated with Hadoop, so it provides more powerful scalability and data operation performance. And as cloud computing technology continues to become an important pillar supporting the development of information technology in various industries, due to the huge advantages of HBase database, more and more scenarios need to use Philippine relational database such as HBase database for data storage and management. [0003] Taking invoice data as an example, according to effective statistics, up to now, ther...
