Embodiment Construction

[0048] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0049] The embodiment of the present invention considers that when there is a large amount of data in the original database and the overall data needs to be migrated to the new database, the following problems will exist if the overall copy of the database is adopted: the overall copy is very time-consuming, and it may also be caused by external reasons. The phenomenon of copy interruption; the overall copied data is prone to abnorm...

Abstract

The invention discloses a data migration method, a device, an apparatus and a storage medium. The method comprises steps: determining a page corresponding to data in an original database; determininga display level of each page according to a set level setting rule; splitting each data according to the display hierarchy; migrating the split data to the target database in parallel. The data migration scheme of the embodiment of the invention splits the data in the database to be migrated according to the display hierarchy, and carries out parallel copy on the split data, thereby improving thecopy efficiency and correctness of the data. Because the invention splits the data according to the display level, after the data of each display level is copied in parallel, the copied data can be accessed by the system, thereby accelerating the loading efficiency of the data, facilitating the user to see the page data more quickly, and improving the data presentation efficiency.

Description

technical field [0001] The present invention relates to the field of big data, in particular to a data migration method, device, equipment and storage medium. Background technique [0002] Core Data is a relatively efficient database framework, but Core Data is not a kind of database. It still uses Sqlite3 to store data at the bottom. Core Data can manipulate data as objects, and developers don't need to care about how data is stored on disk. It will save the instance of the managed object NSManagedObject class or an instance of an NSManagedObject subclass located in the managed object context NSManagedObject Context to one or more managed objects held by the persistent storage coordinator NSPersistentStoreCoordinator through the NSManagedObjectModel managed object model NSPersistentStore in the persistent store. [0003] However, when the data type changes, is deleted or modified, and the old data saved before the data modification is queried again, the database read will...
