Pool exhausted, Java 21 and Virtual Threads about lettuce HOT 3 OPEN

I am also interested in this. I could not find a clear documentation on how to use virtual threads in lettuce. Appreciate a good reference.

from lettuce.

Hi, I am getting Pool exhausted when I pass a ClientResources which does use an executor with virtual threads.

java.util.concurrent.CompletionException: java.util.NoSuchElementException: Pool exhausted
	at java.base/java.util.concurrent.CompletableFuture.encodeThrowable(Unknown Source) ~[?:?]
	at java.base/java.util.concurrent.CompletableFuture.uniApplyNow(Unknown Source) ~[?:?]
	at java.base/java.util.concurrent.CompletableFuture.uniApplyStage(Unknown Source) ~[?:?]
	at java.base/java.util.concurrent.CompletableFuture.thenApply(Unknown Source) ~[?:?]
	at io.lettuce.core.support.AsyncConnectionPoolSupport$1.acquire(AsyncConnectionPoolSupport.java:189) ~[lettuce-core-6.3.2.RELEASE.jar:6.3.2.RELEASE/8941aea]

This is my java code,

var executor = Executors.newThreadPerTaskExecutor(Thread.ofVirtual().factory());
EventLoopGroup customEventLoopGroup = new NioEventLoopGroup(0, executor);
var clientResources =
        ClientResources.builder().eventExecutorGroup(customEventLoopGroup).build();
RedisClient.create(clientResources, ...);

how can I fix this?
I am using lettuce-core-6.3.2.RELEASE.jar running on a linux container.
Thanks!

Hey I'm not quite sure if I know the solution, but you might want to look into
newVirtualThreadPerTaskExecutor()
