> There needs to be a documentation that explains how to use the new serializer
> upgrade APIs in {{TypeSerializer}}, and how the methods work with
> checkpoints. This documentation should probably be placed under "Application
> development --> Streaming --> Working with State".
> Ideally, it should also come with a minimal example for users that perhaps
> use serialization frameworks that already have built-in backwards
> compatibility (such as Thrift).
