> 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.
