------------------------------------
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.
