Instant response and work in the background

[uPagge]

I receive a webhook event from an external service, according to its agreement, I have to reply to it with code 200 when I received the message, if it does not receive code 200 within 30 seconds, it sends the request again. My application logic can run longer than 30 seconds, because of this I get repeated events. Is there any way I can write the Uni pipelines in such a way that it responds instantly from the controller, but continues to execute my logic.

I tried to do something like this. But in that case I get a DB timeout after some number of queries. There is no such problem when pipelining is not interrupted.

public Uni<Response> updateReceived() {
        Uni<Response> response = Uni.createFrom().item(Response.ok().build());

        Uni.createFrom().voidItem()
                .invoke(() -> {
                 
                })
                .call(
                       
                )
                .runSubscriptionOn(Infrastructure.getDefaultExecutor())
                .subscribe().with(ignored -> {}, Throwable::printStackTrace);

        return response;
    }
