Embodiment Construction

[0019] In order to solve the following problems in the prior art: the existing data migration tool supports relational data well, but does not support the original BLOB type data, and cannot achieve efficient data migration; the present invention provides a data migration method and storage media, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] The first embodiment of the present invention provides a data migration method, the flow of the method is as follows figure 1 As shown, including steps S101 to S103:

[0021] S101, divide the Hbase database into multiple predetermined areas;

[0022] S102, converting the relational data in the predetermined relational database into data in TLV format, and storing it in a preset TLV format file;

Abstract

The invention discloses a data migration method and a storage medium. The method comprises the steps that an Hbase database is divided into multiple predetermined regions; relational data in a predetermined relational database is converted into TLV-format data, and the TLV-format data is stored into a preset TLV-format file; and the data in the preset TLV-format file is concurrently migrated to the predetermined regions through predetermined migration instances. According to the method, the relational data in the predetermined relational database is converted into the TLV-format data, and therefore original BLOB-type data also can be migrated; and in the migration process, the Hbase database is partitioned, therefore, the data can be migrated concurrently, data migration time is greatly shortened, and the problem that in the prior art, existing data migration tools can well support the relational data but do not support the original BLOB-type data, and consequently efficient data migration cannot be realized is solved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data migration method and a storage medium. Background technique [0002] At present, data storage and data analysis based on Hadoop (a distributed system infrastructure) big data ecological environment has become the mainstream direction of massive data storage and data analysis. The storage of massive data is a basic advantage of the Hadoop cluster environment over relational database storage, but how to migrate the original massive data from the relational database to the Hadoop cluster environment is still an urgent problem to be solved. In response to such problems, various application vendors and open source communities have proposed corresponding solutions, such as the popular and general sqoop tool (an open source tool, mainly used for data transfer between Hadoop and traditional databases), etc. , but these methods or tools, after preliminary tests, found that the exist...
