> Allow field annotations to define TypeInformation

> Key: FLINK-7859
> URL: https://issues.apache.org/jira/browse/FLINK-7859
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Affects Versions: 1.3.2
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
> Labels: stale-assigned
>
> Right now it is impossible to define custom TypeInformation for specific
> fields. For example, we cannot provide information about a {{Row}} type that
> is a field of Scala case class. An option would be to allow fields to be
> annotated with {{@TypeInfo}} such that a type information can be provided.
> {code}
> case class Test(a: Int, b: String, @TypeInfo(classOf[MyRowFactory]) c: Row)
> {code}
