Hi,
Here is my code:
Source<Product, NotUsed> missedProductSource =
Source.from(missedProducts) ;
final RunnableGraph<akka.NotUsed> missedTo =
missedProductSource.mapAsyncUnordered(5, p->{
try {
return stopProductDisplay(p.productNo, p.id);
} catch (Throwable t ) {
Logger.error(t.getMessage(), t);
return CompletableFuture.completedFuture((Void)null);
}
}).to(Sink.ignore()) ;
missedTo.run(materializer) ;
Where stopProductDisplay's return type is CompletionStage<Void>.
The size of missedProducts is more than 30,000. but the stream only
processed 5 elements, then stop working. No error logged out.
I cannot figure out the reason.
What is wrong with the above code, or how to debug the issue?
Thanks for your help.
