> Key: FLINK-7409
> URL: https://issues.apache.org/jira/browse/FLINK-7409
> Project: Flink
> Issue Type: Improvement
> Components: Webfrontend
> Affects Versions: 1.4.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Minor
>
> The {{WebRuntimeMonitor}} contains a lot of blocking operations where it
> retrieves a result from the {{JobManager}} and then waits on the future to
> obtain the result. This is not a good design since we are blocking server
> threads with that. Instead I propose to follow a more reactive approach where
> the {{RequestHandler}} returns a {{CompletableFuture}} of {{FullHttpResonse}}
> which is in the completion handler written out to the channel.
