Lakshmi Rao commented on FLINK-11254:
-------------------------------------
Thanks for this effort [~tzulitai] and [~klion26]. To be clear, this affects
other versions of Flink as well? We see issues in trying to migrate from Rocks
to Filesystem backend in Flink 1.5 as well.
> Unify serialization format of savepoint for switching state backends

> Key: FLINK-11254
> URL: https://issues.apache.org/jira/browse/FLINK-11254
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Affects Versions: 1.7.1
> Reporter: Congxian Qiu(klion26)
> Assignee: Congxian Qiu(klion26)
> Priority: Major
>
> For the current version, the serialization formats of savepoint between
> HeapKeyedStateBackend and RocksDBStateBackend are different, so we can not
> switch state backend when using savepoint. We should unify the serialization
> formats of the savepoint to support state backend switch.
