Problems solved by technology

This method is not suitable for business peak periods, because data migration does not converge during business peak periods, and it is difficult to meet the conditions for data migration completion; and at the end of data migration, the database service needs to be stopped. For distributed storage systems, data migration involves many machines. As long as one of the machines has a problem, the data migration cannot be completed, resulting in extended and unpredictable service stop times

Abstract

The present disclosure provides a data migration method, device and electronic equipment of a distributed storage system. The system includes a first node and a second node respectively used for storing data, and the route for the requester to operate the target data leads to For the first node, the method includes: triggering data migration in response to the operation request sent by the requesting end for the target data, and caching the operation request queue sent by the requesting end before switching the route; when the When the first node finishes processing the operation requests for the target data accumulated before the data migration, switch the route from the first node to the second node, and release the operation request queue to the second node. two nodes. The embodiments of the present disclosure can meet the data migration requirements during the business peak period, avoid the occurrence that the requesting end cannot accept the service during the data migration process, and ensure the consistency of the data before and after the data migration.

Description

technical field [0001] The present disclosure relates to the field of data storage, and in particular to a data migration method, device and electronic equipment for a distributed storage system. Background technique [0002] In the field of information technology, the storage and management of data has always been of great significance. In many cases, it is necessary to migrate data due to various business requirements (for example: expanding the capacity of the database, reducing the capacity of the database, and updating the database). [0003] The data migration scheme in the existing technology usually directly synchronizes data between the data source and the data target. After the synchronization reaches a certain ratio, the database service is temporarily stopped, and then the remaining data is continued to be synchronized and the route is switched to realize data migration. This method is not suitable for business peak periods, because data migration does not conve...
