RE: Tomcat 10 and virtual thread

THALES GROUP LIMITED DISTRIBUTION to email recipients

Hello Christopher,

Thanks for the explanation.
So :
<Connector port="8080" protocol="HTTP/1.1"
                 connectionTimeout="20000"
                 redirectPort="8443"
                 maxParameterCount="1000"
                 useVirtualThreads="true" />

is equivalent to
- define an executor  <Executor name="virtualThread"
                                                        className="org.apache.catalina.core.StandardVirtualThreadExecutor" />
- use it
<Connector executor="virtualThread" port="8080" protocol="HTTP/1.1"
                      connectionTimeout="20000"
                      redirectPort="8443"
                      maxParameterCount="1000"/>
right ?

If the answer is yes, it means that if we have useVirtualThreads set to true, than the executor used will be most probably
the org.apache.catalina.core.StandardVirtualThreadExecutor class for the executor.
right ?

Best Regards.

This uses <Connector> to auto-create an <Executor> The useVirtualThreads attribute just tells Tomcat to create an <Executor> that uses the virtual thread executor class.
