executing CompletableFuture.supplyAsync on event loop?

[Igor Spasić]

What are the issues of executing  CompletableFuture.supplyAsync() on event loop?

[Clement Escoffier]

Hi,

The issue is that other callbacks are not necessary called on the same thread (event loop thread). For instance, you have a CompletableFuture, but then you do something like: future.acceptAsync(x -> {

// Called using a thread from a fork/join executor

});

If you look at https://github.com/cescoffier/vertx-completable-future it gets the current context and ensure that all callbacks are called using the same thread, so:

future.acceptAsync(x -> {

// Called on the event loop

});
