TraceId propagation to the new thread local

From that description it sounds like the use-case is pretty complex, so would be great to have some simple project from you to play with.
Does it work well if you change that CompletableFuture<String> to just String?

[TJackler]

Yes, it works correctly without CompletableFuture.

[artembilan]

OK. So, then my request for a simple project is the next step what we can do over here.

[artembilan]

According to the code there is no observation on sending a reply from the Rabbit listener method, so I'm failing to understand how it may work without a CompletableFuture.
Do you still think you would have a chance to share with us some project to let us reproduce?
Thanks

Hi, not sure if this will help, but in the past I used the overloaded CompletableFuture methods that take an Executor.

I create my executor like the following example:

ExecutorService executorService = new TraceableExecutorService(beanFactory, Executors.newFixedThreadPool(10));

then:

CompletableFuture.runAsync(() -> doStuff(), executorService)
