Aurora Single Level Store Operating System

The Aurora Single Level Store provides transparent persistence for applications based on lightning fast incremental checkpoints. Aurora checkpoints are either stored on-disk in a custom object store or in memory for debugging applications. Unlike older single level stores Aurora provides a file system namespace into the store to enable backwards compatibility.
