   @rabbah you mean like this?:
   
   ```scala
   Future {
     blocking( producer.send(record) )
   } andThen {
     case Success(futureMetadata) =>
       try {
         produced.success(futureMetadata.get)
       } catch {
         case e: ExecutionException =>
           produced.failure(e.getCause)
       }
     case Failure(t) =>
       produced.failure(t)
   }
   ```
   
   As the return type of `producer.send(record)` is a `java.util.concurrent.Future<RecordMetadata>`, do you have any better idea to finish a scala `Promise` with a java `Future`?
