----------------------------------
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.
