pymysql to connect to db, when tring to get a large data from database, use pymysql.cursors.SSCursor or pymysql.cursors.SSDictCursor.[1] But it will still meet timeout error, so if get large results from database, I will use the default cursor type and use fetchall to get all data so that we won't have any errors.we can set custom settings for every spider, for more info,pls visit https://docs.scrapy.org/en/latest/topics/spiders.html
