Devoxx Greece 2024 - Butcher Virtual Threads like a pro! by PIOTR PRZYBYL

Here is the meta description: "Join Piotr Przybyl to learn how to master Virtual Threads like a pro, covering the benefits, constraints, and best practices for using this powerful concurrency feature in Java 21."

Key takeaways
  • Virtual threads are not a magic solution for every problem, and there is no one-size-fits-all approach to using them.
  • Virtual threads are part of the standard feature in Java 21, and structured concurrency and scope values are still in preview.
  • Virtual threads are cheap to start, take less memory, and are carried by platform or operating system threads under the hood.
  • Virtual threads are unmounted by the scheduler when waiting for IO, which can lead to better performance.
  • Immutable things are usually faster than mutable things, and virtual threads can simplify reasoning and improve performance.
  • Virtual threads can be used with synchronize and native, and can be reused and mixed with other concurrency models.
  • Structured concurrency is about having better idioms for multithreaded code and eliminating thread leaks and cancellation delays.
  • Virtual threads can be used to handle back pressure, but a poor managed solution can lead to issues.
  • Virtual threads can be used to scale applications better, but individual requests may not be handled faster.
  • Pinning virtual threads can lead to issues, and it’s recommended to avoid pinning them.
  • Virtual threads can be used with Elasticsearch client, but it’s recommended to use the latest version.
