Abstract

The invention provides a Hbase data online migration method and device. The method includes the steps that from a first moment, data of a first cluster is mirrored to a second cluster; at a second moment after mirroring is ended, bilateral synchronization of the first cluster and the second cluster is started, and updated data of the first cluster and updated data of the second cluster after the second moment are synchronized between the first cluster and the second cluster; updated data of the first cluster in the time period from the first moment to the second moment is copied to the secondcluster. Under the condition that write access of an original cluster is not stopped, data online migration of uninterrupted services is achieved.

Description

Technical field [0001] This application relates to Internet data service technology, and in particular to an Hbase data online migration method and device. Background technique [0002] Hadoop Database (HBase) is a highly reliable, high-performance, column-oriented, and scalable distributed storage system. Using HBase technology, large-scale structured storage can be built on a cheap PC Server. Cluster. [0003] When HBase data is migrated offline, the data is copied from the original cluster to the target cluster. When the data is migrated online, it is usually necessary to stop write access to the original cluster, which will interrupt the front-end business. Summary of the invention [0004] In view of this, the embodiments of the present application provide an online data migration method and device of Hbase to solve the technical problem that the online data migration of Hbase will interrupt the front-end business. [0005] According to one aspect of the embodiments of the pres...
