Ufuk Celebi commented on FLINK-1747: ------------------------------------ [~StephanEwen], was this a duplicate of FLINK-2041? > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
