> Key: FLINK-11772
> URL: https://issues.apache.org/jira/browse/FLINK-11772
> Project: Flink
> Issue Type: Bug
> Components: DataStream API
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.8.0
>
>
> All of the changes done to managed state surrounding how we no longer
> Java-serialize serializers anymore and only write the serializer snapshot, as
> well as how serialization compatibility checks should go through the new
> {{TypeSerializerSnapshot}} / {{TypeSerializerSchemaCompatibility}}
> interfaces, was not reflected to timers.
> This was mainly due to the fact that timers were not handled by state
> backends (and were therefore not managed state) in the past, and were handled
> in an isolated manner by the {{InternalTimerServiceSerializationProxy}}.
> The {{InternalTimerServiceSerializationProxy}} therefore needs to be updated
> accordingly.
