Question: I'm trying to implement change data capture (CDC) on the Oracle Source Database to achieve the real-time staging database and loading this changed data into a specific "data layer" through the extract, transform and load (ETL) tool for the intra-day reporting. I found two types of methods for CDC: synchronous and asynchronous. Asynchronous further classified into four methods: hotlog, distributed hotlog, autolog archived and autolog online.
