Stephan Ewen commented on FLINK-1764:
-------------------------------------

The chained filter invokable does that in my case. Once in the {{collect()}} method, once
in the {{filter()}} method.

> 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.
