Introduction As previously explained, CDC (Change Data Capture) is an essential step to extract change events from an OLTP application to make them available to other modules in an enterprise system (e.g. caches, data warehouse). While Debezium is the most efficient way of doing CDC, it might be that you need a simpler solution in your project. Hibernate Envers is a Hibernate ORM extension that allows you to capture change events in no time. In this article, we are going to see the most efficient way of using Hibernate Envers.
Introduction In OLTP (Online Transaction Processing) systems, data is accessed and changed concurrently by multiple transactions and the database changes from one consistent state to another. An OLTP system always shows the latest state of our data, therefore facilitating the development of front-end applications which require near real-time data consistency guarantees. However, an OLTP system is no island, being just a small part of a larger system that encapsulates all data transformation needs required by a given enterprise. When integrating an OLTP system with a Cache, a Data Warehouse or an In-Memory… Read More
