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()
from lettuce.
Hey @jkvargas ,
Executor executor = Executors.newThreadPerTaskExecutor(Thread.ofVirtual().factory()); EventLoopGroup customEventLoopGroup = new NioEventLoopGroup(0, executor); var clientResources = ClientResources.builder().eventExecutorGroup(customEventLoopGroup).build(); try (RedisClient clusterClient = RedisClient.create(clientResources, redisURI)) { StatefulRedisConnection<String, String> connection = clusterClient.connect(); connection.sync().set("key", "value"); }```
I tried your code and it worked for me, could this be some environment issue with your JVM / JDK?
Hey I'm not quite sure if I know the solution, but you might want to look into
newVirtualThreadPerTaskExecutor()
Both newVirtualThreadPerTaskExecutor()
and newThreadPerTaskExecutor()
should do the job, see this blog post.
