> Currently, any configuration for serializers that you are using when writing a State Processor API job will be shared with the serializers that are used for writing a savepoint. However, your normal job shouldn't necessarily depend on (helper) classes that you only use in the StateProc API job.
> By default, for example, {{ExecutionConfig#autoTypeRegistrationEnabled = true}} and thus classes like {{org.apache.flink.runtime.checkpoint.OperatorSubtaskState}} will be registered with Kryo and will thus also be needed when reading the created savepoint if you have Kryo serialization in your job.
> This particular instance can be worked around by calling {{ExecutionConfig#disableAutoTypeRegistration()}} but the problem is probably bigger and extends to other type registrations, e.g. POJOs, as well.
