GitHub user polarisGitHub edited a discussion: [Q/A][Java SDK (Component)] For
asynchronous calls, should I use asyncCall or virtual threads?
### Pre-check
- [ ] I am sure that all the content I provide is in English.
### Apache Dubbo Component
Java SDK (apache/dubbo)
### Details
Which way is better?
```java
try (var executor = Executors.newVirtualThreadPerTaskExecutor()) {
Future<A> fa = executor.submit(() -> remoteService.query(req));
// do somethings
A a = fa.get();
Result result = future.get();
}
```
```java
CompletableFuture<Result> future = RpcContext.getServiceContext().asyncCall(()
-> remoteService.query(req));
// do somethings
Result result = future.get();
```
