Virtual Threads (Project Loom) have been introduced in Java 21+ to simplify concurrent programming and improve performance for I/O-heavy applications.
Virtual threads are lightweight threads managed by the JVM, allowing for the execution of thousands or even millions of concurrent tasks without blocking resources.
Benefits of using virtual threads include lightweight concurrency, simplified code without complex thread pooling logic, non-blocking behavior ideal for I/O-bound services, and compatibility with existing Java APIs.
Virtual threads are suitable for web applications, database-heavy microservices, concurrent data processing, and server-side batch jobs.
