Method and system for synchronizing metadata under mass network data environment

Abstract

The embodiment of the invention provides a method and a system for synchronizing metadata under a mass network data environment. The method comprises the following steps: after the metadata inside a metadata base list in a center node server are updated to a second stable version number from a first stable version number, sending a notification message to sub-node administration equipment, wherein the second stable version number is greater than the first stable version number; after the notification message is received by the sub-node administration equipment, obtaining the metadata base list from the center node server, wherein the version number of the metadata inside the metadata table list is the second stable version number; and sending the obtained metadata table list to the sub-node server by the sub-node administration equipment so that the metadata inside the center node server and the metadata inside the sub-node server are synchronized. According to the method and the system, the metadata inside the metadata table list in the system for synchronizing the metadata are synchronized in time.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a metadata synchronization method and system in a massive network data environment. Background technique [0002] Metadata broadly refers to all basic resource data. In the field of metadata management, some relatively mature management solutions have been applied to metadata management systems with different backgrounds, different types of data storage, and different requirements for data accuracy. [0003] At present, the methods of metadata management mainly include: the maintenance personnel of the metadata table perform operations such as adding, deleting, modifying, and querying the metadata of the metadata table stored in the central node server according to the change of metadata. The preset cycle downloads the metadata table from the central node server, and stores the downloaded metadata table in the child node server; when the user needs to obtain the metadata table...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that after maintenance personnel perform operations such as adding, deleting, modifying, and querying the metadata of the metadata table, the local administrator obtains the metadata table at a preset cycle. When the time interval of the preset cycle is relatively long, the local administrator The latest version of the metadata table cannot be obtained in time, resulting in inconsistent metadata between the metadata table in the child node server and the metadata table in the central node server
