入库items 会出现重复

[oyjcmyn]

/usr/local/python3/lib/python3.11/site-packages/pymysql/connections.py:846: UserWarning: Previous unbuffered result was left incomplete
warnings.warn("Previous unbuffered result was left incomplete")
感觉与这个有关系，有设置了REQUEST_FILTER_SETTING 为 filter_type=3
同时在入库前，有进行一行mysql find查询hash，但是最后还是会重复，从重复的入库时间来看，在同秒进入的。
`hash = torrent['info_hash']

    sql = f"SELECT `t_id`,`t_hash`,`t_douban_id`,`t_imdb_id` FROM `mv_torrent` WHERE t_hash='{hash}'"
    dbid = self.db.find(sql, 1)

    if not dbid and hash:

        item = MvTorrentItem()
        # item.t_add_time = tools.get_current_date()
        item.t_update_time = tools.get_current_date()`

是不是我再加一个ITEM_FILTER_ENABLE=True设置能解决？设置好__unique_key__
