        public SkipListMemTableConfig setLookahead​(long lookahead)
        Sets lookahead for SkipList

        lookahead - If non-zero, each iterator's seek operation will start the search from the previously visited record (doing at most 'lookahead' steps). This is an optimization for the access pattern including many seeks with consecutive keys.
        Returns:
        the current instance of SkipListMemTableConfig
