> Key: FLINK-29030
> URL: https://issues.apache.org/jira/browse/FLINK-29030
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.16.0
>
>
> Users are encouraged to use POJO types, that will be serialized by the
> PojoSerializer which supports schema evolution.
> If a user does not use a POJO we print an info message, linking to the docs
> and citing potential performance issues.
> However, no such message is printed if a POJO _contains_ a generic type.
> As a result there may be users out there believing to have optimal
> performance and support for schema evolution since, after all, they are able
> to use the POJO serializer, when this may not be the case.
