Gyula Fora created FLINK-2335: --------------------------------- Summary: Rework iteration construction in StreamGraph Key: FLINK-2335 URL: https://issues.apache.org/jira/browse/FLINK-2335 Project: Flink Issue Type: Improvement Components: Streaming Reporter: Gyula Fora Assignee: Gyula Fora
Currently the nodes representing the extra sinks and sources are incrementally added to the streamgraph when the user creates the iterative parts of the program. This makes it difficult to enforce different partitioning schemes on the feedback edges and also makes it virtually impossible to handle more iteration heads with different parallelism. The actual nodes in the streamgraph for the iteration sinks/sources should only be created when the program is finalized after the user calls execute and before we create the jobgraph. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
