public abstract java.lang.String getPath()

loadExisting
```
public abstract void loadExisting()
```
Load all Key/Value pairs that can be found on the backend.

load
```
public abstract byte[] load(Value v)
```
Value should already be persisted to disk. A racing delete can trigger a failure where we get a null return, but no crash (although one could argue that a racing load and delete is a bug no matter what).

public abstract Value lazyArrayChunk(Key key)

Lazily manifest data chunks on demand.
