>             Project: Flink
>          Issue Type: Improvement
>          Components: Optimizer
>    Affects Versions: master
>            Reporter: Ufuk Celebi
>            Priority: Minor
>
> The deadlock detection in the optimizer, which places pipeline breaking caches has become redundant with recently added changes. We now use blocking data exchanges for branching programs, which are merged again at a later point.
> Therefore, we can start removing the respective code in the optimizer.
