> - Use NavigableSet<String> instead of ArrayList<String> to store natively ordered and unique row-key instead of ugly repeatedly using `Collections.sort` or check whether existing on business logic layer, in fact because the raw-key is originally sorted in hbase, the change won't consume any more computational complexity.
> - Verify prefix in hbase region level using prefix filter instead of comparing String in client side.
