    When scanning for a prefix the scan should stop immediately after the the last row that has the specified prefix.

    When scanning for a prefix the scan should stop immediately after the the last row that has the specified prefix. This method calculates the closest next row key immediately following the given prefix.

    To scan rows with a given prefix, do

    scan(prefix, nextRowKeyForPrefix(prefix))
    prefix

    the row key prefix.

    returns

    the closest next row key immediately following the given prefix.
