Java Platform Threads threads are expensive. With the release of JDK 21, Java Virtual Threads provides an alternative to
Reactive Programming to scale your Java applications, simplifying how you can write, debug and maintain Java enterprise applications.

With Java Virtual Threads, we can now return to writing a synchronous, blocking database access logic to avoid such complexity imposed by Reactive Programming. Nevertheless, it's possible to maximize such gains using pipelined database operations so that a database call returns immediately, freeing the client code to process additional functions.

This session provides a walkthrough of reactive programming, pipelined database operations, and synchronous programming using Java Virtual Threads.
