Event Sourcing in Microservices Using Spring Cloud and Reactor
Mostly all databases today support some form of high availability clustering. Most database products will provide a list of easy to understand guarantees about a system’s consistency model. A first step to achieving safety guarantees for stronger consistency models is to maintain an ordered log of database transactions. This approach is pretty simple in theory. A transaction log is an ordered record of all updates that were transacted by the database. When transactions are replayed in the exact order they were recorded, an exact replica of a database can be generated.
