[jira] [Created] (FLINK-1565) Document object reuse behavior

Fabian Hueske created FLINK-1565:
------------------------------------

             Summary: 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
             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.
