Java 19 And Beyond | New Parallelism Through Virtual Threads And Structured Concurrency
Java 19 was just released, and Java 21 is coming up fast too. I like to keep an eye on things coming up, so I wanted to share with you a video on parallelism features coming up in future Java releases. Java 19 parallelism will bring you two very cool things that originate from project Loom: Virtual Threading, and Structured Concurrency. In this little video, I'll explain what they are, and what they are good for, and will run a million threads in parallel just because I can. Join me for 15 minutes and perhaps learn something new.
