---------------------------------------
Fix Version/s: 1.12.0
Release Note: The `boolean isOuterSnapshotCompatible(TypeSerializer)` on
the `CompositeTypeSerializerSnapshot` class has been deprecated, in favor of a
new `OuterSchemaCompatibility resolveOuterSchemaCompatibility(TypeSerializer)`
method. Please implement that instead. Compared to the old method, the new
method allows composite serializers to signal state schema migration based on
outer schema and configuration.
Resolution: Fixed

>
> Compatibility of composite serializers is governed by the overall resolved
> compatibility of all its nested serializers, as well as any additional
> configuration (or what we call the "outer configuration" or "outer snapshot").
> The compatibility resolution logic for these composite serializers is
> implemented in the {{CompositeTypeSerializerSnapshot}} abstract class.
> One current limitation of this base class is that the implementation assumes
> that the outer configuration is always either compatible, or incompatible.
> We should relax this to also allow signaling migration, purely based on the
> outer configuration. This is already a requirement by FLINK-16998.
