-------------------------------------------

             Summary: All implementations of deprecated TypeSerializer#ensureCompatibility method should be removed
                 Key: FLINK-11741
                 URL: https://issues.apache.org/jira/browse/FLINK-11741
             Project: Flink
          Issue Type: Improvement
          Components: Type Serialization System
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai
             Fix For: 1.8.0


All remaining implementations of the deprecated {{TypeSerializer#ensureCompatibility}} method should be removed.

Some previously may not have been removed yet because of various limitations causing the old snapshot class not being able to redirect schema compatibility checks to new snapshot class (e.g. the old snapshot class was shared across serializers).

These problems should be addressable now with the auxiliary {{SelfResolvingTypeSerializer}} / {{LegacySerializerSnapshotTransformer}} interfaces.
