Embodiment Construction

[0024] In the existing technology, the knowledge base metadata changes generated by operators other than the operation team through the Create / Read / Update / Delete Application Programming Interface (Create / Read / Update / Delete Application Programming Interface, CRUD API) cannot be integrated with the metadata management system Changes in the repository trigger change events, and the subscription interface for knowledge base metadata cannot obtain corresponding knowledge base metadata updates in a timely manner. Therefore, each system other than the metadata management system cannot accurately acquire the update information of the metadata of the knowledge base in real time.

[0025] In addition, since the subscription interface of the knowledge base metadata runs together with the background management interface, multi-node deployment of the subscription interface is not possible. For distributed computing frameworks (such as SPARK computing engine, etc.), the multi-node requireme...

Abstract

The invention discloses a knowledge base metadata sending method and device and a readable storage medium. The knowledge base metadata sending method comprises the steps of sensing whether a change triggering event corresponding to knowledge base metadata occurs or not; when the change trigger event is sensed, calling Hook corresponding to an abstract model of a metadatabase according to the change trigger event; and sending corresponding knowledge base metadata to a target user corresponding to the change trigger event through a unified metadatabase interface. By adopting the scheme, a user can accurately obtain the update information of the metadata of the knowledge base in real time.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a knowledge base metadata sending method and device, and a readable storage medium. Background technique [0002] Metadata, also known as intermediary data and relay data, is data describing data, mainly describing data attributes (Property) information, used to support functions such as indicating storage location, historical data, resource search, file recording, etc. . At the same time, metadata is also a kind of structured data (Structured Data) used to provide information about certain resources. Among them, knowledge base metadata can usually contain descriptive information on the real world, and knowledge base metadata provides necessary information related to system business for the operation of real world data collection and processing systems. [0003] Operators can usually edit the generation rules of knowledge base metadata, and the metadata mana...
