-------------------------------------
Assignee: Robert Metzger
> Document object reuse behavior
> ------------------------------
>
> Key: FLINK-1565
> URL: https://issues.apache.org/jira/browse/FLINK-1565
> Project: Flink
> Issue Type: Improvement
> Components: Documentation
> Reporter: Fabian Hueske
> Assignee: Robert Metzger
> Fix For: 0.9
>
>
> The documentation needs to be extended and describe the object reuse behavior
> of Flink and its implications for how to implement functions.
> The documentation must at least cover the default reuse mode:
> * new objects through iterators and in reduce functions
> * chaining behavior (objects are passed on to the next function which might
> modify it)
> Optionally, the documentation could describe the object reuse switch
> introduced by FLINK-1137.
