Abstract

The invention provides a method, device and system for updating metadata. The method comprises the following steps: determining cache data and metadata corresponding to the cache data, and caching the determined metadata; when the cached metadata meets an updating condition, generating a message by using the cached metadata, and sending the message to an external metadata server to update metadata stored in the external metadata server through the message. According to the method, by means of caching the metadata first and generating the message through the cached metadata, the frequent updating processes of the metadata server are changed into a one-time updating process, so that the metadata server updating frequency is effectively reduced, and the system efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and system for updating metadata. Background technique [0002] Metadata, also known as intermediary data and relay data, is a kind of data that describes data, mainly information that describes data attributes, and is used to support functions such as indicating storage locations, historical data, resource search, and file records. [0003] In most applications, such as using social shopping sites, radio and television, and online videos, a large number of small memory files such as text, pictures, and music will be generated. When writing each small memory file, each small memory file must be written The metadata corresponding to the memory file is updated to the metadata server. [0004] However, small memory files flow quickly and are frequently operated, resulting in frequent updates of the metadata server, resulting in low system performance. C...
