Tzu-Li (Gordon) Tai closed FLINK-11755.
---------------------------------------
Resolution: Fixed
Release Note:
The {{ensureCompatibility}} method have been removed from {{TypeSerializer}}.
All other related classes, such as {{CompatibilityResult}}, has also been
removed.
Please refer to the class-level Javadoc of {{TypeSerializer}} for instructions
on how you should update your serializer implementations to adapt to the new
serialization compatibility abstractions {{TypeSerializerSnapshot}} and
{{TypeSerializerSchemaCompatibility}}.
Merged.
1.8.0: ae6249789c8aac67f6fd9bde05c1f45e64dd7afa
1.9.0: 572b9d6250b8bcdd5d9968ab12a223a3daf762f1

> Project: Flink

> Components: API / Type Serialization System
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Fix For: 1.8.0
>
>
> With {{TypeSerializer#canEqual}} removed in 1.8.0 and the interface already
> broken for backwards compatibility, it would make sense to also remove the
> {{ensureCompatibility}} method.
> This method was already deprecated for a whole major version (since 1.7.0)
> already.
> The effect of removing this method completely:
> - All restored legacy {{TypeSerializerConfigSnapshot}}'s compatibility checks
> would not be able to go through {{ensureCompatibility}}. Instead, they must
> be redirected to new snapshot classes that implement
> {{TypeSerializerSnapshot}}.
> - If the user already upgraded to the {{TypeSerializerSnapshot}} interface in
> 1.7.x, then this wouldn't be a concern. This only affects users who are still
> on the {{TypeSerializerConfigSnapshot}} interface.
