>
> Most built-in ordered collection data structures in Java (SortedMap, List,
> ...) define a range (submap / sublist) as follows:
> 'from' (inclusive) -> 'until' (exclusive)
> However, the current LevelDbKeyValueStore implementation defines range as:
> 'from' (inclusive) -> 'to' (inclusive)
> While this is not technically incorrect, I think we should change the
> semantics to follow the norm.
> P.S. This can easily be done by changing the '<=' comparison in
> LevelDbRangeIterator to '<'
