> Remove ExecutionConfig field from PojoSerializer
> ------------------------------------------------
>
> Key: FLINK-13876
> URL: https://issues.apache.org/jira/browse/FLINK-13876
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Affects Versions: 1.7.2, 1.8.1, 1.9.0, 1.10.0
> Reporter: Dawid Wysakowicz
> Priority: Minor
> Labels: auto-deprioritized-major
> Fix For: 1.18.0
>
>
> The PojoSerializers stores an instance of ExecutionConfig as internal field,
> even though that the only information it may ever need are the registered
> kryo serializers.
> This has a few drawbacks:
> * It blocks the evolution of {{ExecutionConfig}} as serializers where stored
> in a state. Therefore any change to ExecutionConfig must be backwards
> compatible in respect to java serialization
> * It probably already introduced a bug, as upon restore the Snapshot actually
> recreates the serializer with an empty ExecutionConfig (see
> org.apache.flink.api.java.typeutils.runtime.PojoSerializerSnapshot#restoreSerializer)
> I suggest to remove the field completely and adjust corresponding usages.
