Hands-On Reactive Programming in Spring 5

Advantages of the synchronous model

Even though synchronous data access is not the most efficient way of spending server resources when implementing a persistence layer, it is still a highly valuable approach, primarily when used for building blocking web applications. JDBC, while probably being the most popular and versatile API for accessing data, almost entirely hides the complexity of client-server communications between an application and a database. Spring Data JDBC and Spring Data JPA give even more high-level instruments for data persistence, hiding the tremendous complexity of query translation and transaction management. All of this is battle-tested and considerably simplifies the way in which modern applications have developed. ...
