---------------------------------------
Summary: CoStreamWindow is Dependent on Input Ordering
Key: FLINK-2234
URL: https://issues.apache.org/jira/browse/FLINK-2234
Project: Flink
Issue Type: Improvement
Components: Streaming
Reporter: Aljoscha Krettek
Assignee: Aljoscha Krettek
The implementation depends on elements always arriving in a round-robin
fashion, i.e. element from first input, then element from second input, then
first again and so on (read order is 1,2,1,2...). I don't think this assumption
holds for real-world problems.
For example, CoWindowTest produces wrong results if MockCoContext is modified
to read two elements from input 1 and then one from two (read order
1,1,2,1,1,2...).
