             Summary: Rework record copying logic in streaming API
                 Key: FLINK-1764
                 URL: https://issues.apache.org/jira/browse/FLINK-1764
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 0.9
            Reporter: Stephan Ewen


The logic for chained tasks in the streaming API does a lot of copying of records. In some
cases, a record is copied multiple times before being passed to a function.

This seems unnecessary, in the general case. In any case, multiple copies seem incorrect.
