> While working on async scanner I had some trouble with the extra RPC calls
> that happen to let the Scanner advance 1 row so it skips the last already
> known row.
> This RPC call can be avoided by letting the start key be the last row with an
> appended 0. This saves quite some logic from the scanners and improves
> performance by saving extra RPC calls.
