| description | The invention provides a data delivery method, a data processing method, corresponding equipment, a system and a medium. The data delivery method comprises the steps of obtaining a real-time consumption point location in a pre-write log system WAL log of a database and real-time change data of the database; the real-time change data is change data corresponding to the real-time consumption point location in change data for changing the database; and synchronously sending the real-time consumption point location and the real-time change data to a message system. According to the embodiment of the invention, accurate one-time delivery and accurate one-time processing can be realized, and the accuracy of stream calculation is improved.
本申请提供了一种数据投递方法、数据处理方法及对应的设备、系统、介质。数据投递方法包括：获取数据库的预写日志系统WAL日志中的实时消费点位和数据库的实时变更数据；实时变更数据为对数据库进行变更的变更数据中与实时消费点位对应的变更数据；向消息系统同步发送实时消费点位和实时变更数据。依据本申请实施例，可以实现精确一次投递和精确一次处理，提高流计算的准确性。 |
