------------------------------------
Summary: 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.
