Stephan Ewen created FLINK-3255: ----------------------------------- Summary: Chaining behavior should not depend on parallelism Key: FLINK-3255 URL: https://issues.apache.org/jira/browse/FLINK-3255 Project: Flink Issue Type: Bug Components: Streaming Affects Versions: 1.0.0 Reporter: Stephan Ewen Assignee: Stephan Ewen Fix For: 0.10.1
Currently, operators are chained more aggressively when the parallelism is one. That makes debugging tougher as it changes threading behavior. The benefits are also limited: Real installations where that type of efficiency would be needed would not run in parallelism 1, or would not use a partitioning/broadcast step there (if explicitly required to run parallelism 1). In the future, when we want to allow parallelism to be adjusted dynamically, this will be even more tricky. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
