[jira] [Commented] (KAFKA-14606) Use virtual threads to publish Kafka records

["Divij Vaidya (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-14606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17656562#comment-17656562 ] 

Divij Vaidya commented on KAFKA-14606:
--------------------------------------

I would probably suggest to wait for virtual threads to land in a LTS release before we start modifying existing code base. Meanwhile, if you could perform a prototype with the preview features and demonstrate the impact on Kafka's performance, that will be very helpful to make a decision later on when a LTS release is available.

> Since JDK 19, virtual threads have been added to the JDK as a preview:
> [https://openjdk.org/jeps/425]
> Virtual threads allows you to use the hardware optimal as it is a lightweight thread that runs on a carrier thread (OS thread). When IO happens, the carrier thread is not blocked and can continue doing other work. Currently it doesn't seem to be possible to make `org.apache.kafka.clients.producer.internals.Sender` run on a virtual thread.
> An instance of `org.apache.kafka.common.utils.KafkaThread` is being started. 
> Is it possible to give the possibility to use virtual threads for publishing records?
