See also the xref:server/index.adoc#threadpool[section about configuring the thread pool].
[[threadpool-all-virtual]]
== Module `threadpool-all-virtual`
The `threadpool-all-virtual` module allows you to configure the server-wide thread pool, similarly to what you can do with the <<threadpool,`threadpool`>> Jetty module, so that all threads are virtual threads, introduced as an official feature since Java 21.
CAUTION: Only use this module if you are using Java 21 or later.
If you are using Java 19 or Java 20, use the <<threadpool-virtual-preview,`threadpool-virtual-preview`>> Jetty module instead.
The module properties to configure the thread pool are:
----
include::{jetty-home}/modules/threadpool-all-virtual.mod[tags=documentation]
----
The property `jetty.threadpool.maxThreads` limits, using a `Semaphore`, the number of current virtual threads in use.
Limiting the number of current virtual threads helps to limit resource usage in applications, especially in case of load spikes.
When an unlimited number of virtual threads is allowed, the server might be brought down due to resource (typically memory) exhaustion.
[CAUTION]
====
Even when using virtual threads, Jetty uses non-blocking I/O, and dedicates a thread to each `java.nio.channels.Selector` to perform the `Selector.select()` operation.
Currently (up to Java 22), calling `Selector.select()` from a virtual thread pins the carrier thread.
When using the `threadpool-all-virtual` Jetty module, if you have `N` selectors, then `N` carrier threads will be pinned by the virtual threads calling `Selector.select()`, possibly making your system less efficient, and at worst locking up the entire system if there are no carrier threads available to run virtual threads.

@ -328,32 +328,30 @@ Virtual threads have been introduced as a preview feature in Java 19 and Java 20
The xref:modules/standard.adoc#threadpool-virtual-preview[`threadpool-virtual-preview`] Jetty module provides support for virtual threads in Java 19 and Java 20, and it is mutually exclusive with the `threadpool` Jetty module.
The xref:modules/standard.adoc#threadpool-virtual[`threadpool-virtual`] Jetty module provides support for virtual threads in Java 21 or later, and it is mutually exclusive with the `threadpool` Jetty module.
When using Java 21, there are two Jetty modules available:
* xref:modules/standard.adoc#threadpool-virtual[`threadpool-virtual`]
* xref:modules/standard.adoc#threadpool-all-virtual[`threadpool-all-virtual`]
Both are mutually exclusive with the `threadpool` Jetty module.
If you have already enabled the `threadpool` Jetty module, it is sufficient to remove it by removing the `$JETTY_BASE/start.d/threadpool.ini` file.
When using Java 21 or later, you can enable the xref:modules/standard.adoc#threadpool-virtual[`threadpool-virtual`] module:
The xref:modules/standard.adoc#threadpool-virtual[`threadpool-virtual`] Jetty module provides a mixed thread mode, where platform threads are used to run internal Jetty tasks, but application code is invoked using virtual threads.
The xref:modules/standard.adoc#threadpool-all-virtual[`threadpool-all-virtual`] Jetty module provides a thread mode where all threads are virtual threads, including those used internally by Jetty.
You can enable either module using:
----
$ java -jar $JETTY_HOME/start.jar --add-modules=threadpool-virtual,http
----
After the command above, the `$JETTY_BASE` directory looks like this:
or
[source]
----
$JETTY_BASE
├── resources
│ └── jetty-logging.properties
└── start.d
├── http.ini
└── threadpool-virtual.ini
$ java -jar $JETTY_HOME/start.jar --add-modules=threadpool-all-virtual,http
----
Now you can customize the `threadpool-virtual.ini` file to explicitly configure the thread pool and the virtual threads and then start Jetty:
[jetty%nowrap]
....
[jetty]
setupArgs=--add-modules=threadpool-virtual,http
....
After the command above, the `$JETTY_BASE/start.d/` directory will contain the corresponding `threadpool-virtual.ini` or `threadpool-all-virtual.ini` file.
You can now explicitly configure the thread pool module properties inside the `+*.ini+` file and then start Jetty.

Defaulting the number of reserved threads to zero ensures that the <<execution-strategy-pec,Produce-Execute-Consume mode>> is always used, which means that virtual threads will always be used for blocking tasks.

==== Virtual Threads Support with `VirtualThreadPool`
`VirtualThreadPool` is an alternative to `QueuedThreadPool` that creates only virtual threads (no platform threads).
[,java,indent=0]
----
include::code:example$src/main/java/org/eclipse/jetty/docs/programming/ArchitectureDocs.java[tags=virtualVirtual]
----
Despite the name, `VirtualThreadPool` does not pool virtual threads, but allows you to impose a limit on the maximum number of current virtual threads, in order to limit resource consumption.
Furthermore, you can configure it to track virtual threads so that a xref:troubleshooting/component-dump.adoc[Jetty component dump] will show all virtual threads, including those that are unmounted.
