> Rework Constant Field Annotations
> ---------------------------------
>
> Key: FLINK-1328
> URL: https://issues.apache.org/jira/browse/FLINK-1328
> Project: Flink
> Issue Type: Improvement
> Components: Java API, Optimizer, Scala API
> Affects Versions: 0.7.0-incubating
> Reporter: Fabian Hueske
> Assignee: Fabian Hueske
>
> Constant field annotations are used by the optimizer to determine whether
> physical data properties such as sorting or partitioning are retained by user
> defined functions.
> The current implementation is limited and can be extended in several ways:
> - Fields that are copied to other positions
> - Field definitions for non-tuple data types (Pojos)
> There is a pull request (#83) that goes into this direction and which can be
> extended.
