Oracle CDC (Change Data Capture) Overview
I. Overview of incremental data collection generally refers to the Extract-Data Extraction Section in the ETL process. In addition to ETL, data is usually transferred between different application systems. Under certain environmental conditions, data cannot be directly transferred from one system to another, but data can only be transmitted as an intermediate media using text, the generation of text is limited by the time window, so there are certain requirements on the performance of data collection, that is, data extraction. The following methods are commonly used to increase data collection: 1. timestamps on rows 2. version (Version Numbers on rows) 3. status indication (Status indicat...
