> Key: FLINK-1350
> URL: https://issues.apache.org/jira/browse/FLINK-1350
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Reporter: Ufuk Celebi
> Assignee: Ufuk Celebi
> Fix For: 0.9
>
>
> The current state of runtime support for intermediate results (see
> https://github.com/apache/incubator-flink/pull/254 and FLINK-986) only
> supports pipelined intermediate results (with back pressure), which are
> consumed as they are being produced.
> The next variant we need to support are blocking intermediate results
> (without back pressure), which are fully produced before being consumed. This
> is for example desirable in situations, where we currently may run into
> deadlocks when running pipelined.
> I will start working on this on top of my pending pull request.
