------------------------------------

             Summary: Rename 'checkpoints.savepoint.' package and classes to 'checkpoint.metadata.'
                 Key: FLINK-16247
                 URL: https://issues.apache.org/jira/browse/FLINK-16247
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.11.0


These classes are responsible for the persistence of checkpoint metadata.

Originally, savepoints where the only snapshots with persistent metadata, while checkpoints had the metadata only in memory or in ZooKeeper (Java Serialized).

Nowadays, checkpoints and savepoints both persist metadata in the same way, and hence the package is not actually related to savepoints any more.

Because of that, I suggest to rename the classes from "Savepoint*" to "Metadata*" to better describe what they are really doing.
