public interface CompletedCheckpointStorageLocation
The CompletedCheckpointStorageLocation describes the storage aspect of a completed checkpoint.
It can be used to obtain access to the metadata, get a reference pointer to the checkpoint,
or to dispose the storage location.
Gets the external pointer to the checkpoint. The pointer can be used to resume
a program from the savepoint or checkpoint, and is typically passed as a command
line argument, an HTTP request parameter, or stored in a system like ZooKeeper.
Disposes the storage location. This method should be called after all state objects have
been released. It typically disposes the base structure of the checkpoint storage,
like the checkpoint directory.
