Abstract

The invention discloses a data migration method and device, electronic equipment and a readable storage medium, and belongs to the technical field of data processing. The method comprises the following steps: after a first data copy is started, obtaining a first position identifier, and the first position identifier being a position identifier corresponding to data with the shortest writing time from the current time in data written into a second data copy; obtaining a second position identifier, the second position identifier being a position identifier corresponding to target data in the second data copy, and the write-in time of the target data being later than the write-in time of the data corresponding to the first position identifier; and migrating the target data to the first data copy. According to the invention, the data migration speed can be increased, the data migration time is saved, and the I/O pressure of the nodes in the cluster is reduced.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a data migration method, device, electronic equipment and readable storage medium. Background technique [0002] Message Oriented Middleware (Message Oriented Middleware) refers to middleware that supports and guarantees synchronous / asynchronous message sending and receiving between distributed applications. Message middleware is an independent system software or service program. It is a key software in a computing system, located between user applications, operating systems and network software, and provides a common means of communication for applications. Message middleware provides developers with an application programming interface that is common to all environments. When the application program embeds its function call, it can use the functions of the specific operating system and network environment it runs to perform communication functions ...
