Abstract

The invention belongs to the technical field of big data, and provides a data change message notification method and device, and the method comprises the steps: generating a data relation graph according to metadata in a database where a to-be-notified data change message is located; determining all target nodes of the to-be-notified data change message according to a data relationship graph; andsending the to-be-notified data change message to all the target nodes. According to the method, a task calling relationship and a table dependency relationship are fused to construct a complete'datadependency graph '. Based on the data dependence graph, a traversal algorithm of the graph is utilized to carry out change notification, and the effects of accurately notifying without omitting any person in charge and controlling a notification level to notify in place at one time are achieved.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method and device for notifying a data change message. Background technique [0002] As we all know, the data processing of the data warehouse uses the production data of the transaction system. When production data changes, business development leads to data offline, and data warehouse processing logic changes, etc., it is necessary to notify the downstream data user in time so that the downstream user can make corresponding processing. In the prior art, the flexible notification scheme is as follows: the changer initiates a change notification application, describes the content of the change, and sends it to the direct downstream user according to the invocation dependency of the data processing task. [0003] The above scheme is applicable to the notification of changes in the general trading system, and there are two problems with changes in the data warehouse fi...
