> Untie Checkpoint Externalization from FileSystems
> -------------------------------------------------
>
> Key: FLINK-5897
> URL: https://issues.apache.org/jira/browse/FLINK-5897
> Project: Flink
> Issue Type: Sub-task
> Components: State Backends, Checkpointing
> Affects Versions: 1.2.0
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Fix For: 1.3.0
>
>
> Currently, externalizing checkpoint metadata and storing savepoints depends
> strictly on FileSystems.
> Since state backends are more general, storing and cleaning up checkpoints
> with state backend hooks requires to untie savepoints and externalized
> checkpoints from filesystems.
