Igal Shilman commented on FLINK-21280:
--------------------------------------
This could be solved by modifying:
[https://github.com/apache/flink-statefun/blob/master/statefun-flink/statefun-flink-common/src/main/java/org/apache/flink/statefun/flink/common/UnimplementedTypeSerializer.java#L45,L52]
By simply returning the argument as is.
> Investigate a way to disable object reuse in StateFun
> -----------------------------------------------------
>
> Key: FLINK-21280
> URL: https://issues.apache.org/jira/browse/FLINK-21280
> Project: Flink
> Issue Type: Task
> Components: Stateful Functions
> Reporter: Igal Shilman
> Priority: Major
>
> Currently in StateFun, we require object reuse to be enabled. We are doing it
> because Flink sources can emit arbitrary objects, but the first occurrence of
> the user defined payload serializer happens in a IngressRouterOperator. This
> works due to the fact that this operator is chained to the user, and with
> object reuse, the source output is passed as reference (without any Flink
> serialization) to the IngressRouterOperator.
> Unfortunately JdbcSink requires object reuse to be disabled, and therefore
> can't be used directly with StateFun.
> This issue was first reported on the mailing list:
> [http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Stateful-Functions-JDBC-Sink-Problems-td41265.html]
>
> This issue is about exploring a way to remove the object reuse requirement.
