2. EXPLAIN执行计划:
   +------+---------------+----------------------+--------------+--------+----------------------+----------------------+-----------+-------+--------+------------+------------------+
   | id | select_type | table | partitions | type | possible_keys | key | key_len | ref | rows | filtered | Extra |
   +======+===============+======================+==============+========+======================+======================+===========+=======+========+============+==================+
   | 1 | PRIMARY | | None | ALL | None | None | None | None | 2 | 100 | Using filesort |
   +------+---------------+----------------------+--------------+--------+----------------------+----------------------+-----------+-------+--------+------------+------------------+
   | 2 | DERIVED | user_aukd | None | range | idx_f_date_country_i | idx_f_date_country_i | 8 | None | 5 | 7.14 | Using index |
   | | | ay_stat | | | d,idx_user_activeuse | d | | | | | condition; Using |
   | | | | | | rkeepday_stat | | | | | | where |
   +------+---------------+----------------------+--------------+--------+----------------------+----------------------+-----------+-------+--------+------------+------------------+

3. 索引优化建议：
