Aljoscha Krettek closed FLINK-6096.
-----------------------------------
Resolution: Won't Do
I'm closing this as "Abandoned", since there is no more activity and the code
base has moved on quite a bit. Please re-open this if you feel otherwise and
work should continue.
The checkpoint/savepoint code base has moved on quite a bit since this was
opened.
> Refactor the migration of old versioned savepoints

> Key: FLINK-6096
> URL: https://issues.apache.org/jira/browse/FLINK-6096
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Reporter: Xiaogang Shi
> Assignee: Xiaogang Shi
> Priority: Major
>
> Existing code for the migration of old-versioned savepoints does not allow to
> correctly deserialize those classes changed in different versions. I think
> we should create a migration package for each old-versioned savepoint and put
> all migrated classes in the savepoint there. A mapping can be deployed to
> record those migrated classes in the savepoint so that we can correctly
> deserialize them.
