[jira] [Created] (FLINK-1747) Remove deadlock detection and pipeline breaker placement in optimizer

Ufuk Celebi created FLINK-1747:
----------------------------------

             Summary: Remove deadlock detection and pipeline breaker placement in optimizer
                 Key: FLINK-1747
                 URL: https://issues.apache.org/jira/browse/FLINK-1747
             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.
