             Summary: Add optional annotations for POJOs to specify the order of fields
                 Key: FLINK-1665
                 URL: https://issues.apache.org/jira/browse/FLINK-1665
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 0.8.0, 0.9
            Reporter: Fabian Hueske


The order of fields within a POJO is not well defined.
We could provide an optional annotation such as {{@Position(int)}} to enable the definition of field orders.

The order of fields is relevant when mapping data to POJOs such as when generating POJOs from CSV input, converting POJOs to tuples (for example for the expression API), or when sorting POJOs (see FLINK-1664).
