优化点：
1：尽量使⽤MySQL⾃增ID，InnoDB引擎表是基于B+树的索引组织表，数据记录本⾝被存于主索引（⼀颗B+Tree）的叶⼦节点上。这就要求同⼀个叶⼦节点内（⼤⼩为⼀个内存页或磁盘页）的各条数据记录按主键顺序存放，因此每当有⼀条新的记录插⼊时，MySQL会根据其主键将其插⼊适当的节点
和位置，如果页⾯达到装载因⼦（InnoDB默认为15/16），则开辟⼀个新的页（节点），如果表使⽤⾃增主键，那么每次插⼊新的记录，记录就会顺序添加到当前索引节点的后续位置，当⼀页写满，就会⾃动开辟⼀个新的页。如果使⽤⾮⾃增主键（如果⾝份证号或学号等），由于每次插⼊主键的值近似于随机，因此每次新纪录都要被插到现有索引页得中间某个位置，此时MySQL不得不为了将新记录插到合适位置⽽移动数据，甚⾄⽬标页⾯可能已经被回写到磁盘上⽽从缓存中清掉，此时⼜要从磁盘上读回来，这增加了很多开销，同时频繁的移动、分页操作造成了⼤量的碎⽚，得到了不够紧凑的索引结构，后续不得不通过OPTIMIZE TABLE来重建表并优化填充页⾯。
2：取消所有的索引，尤其是唯⼀索引。（同上）每当有⼀条新的记录插⼊时，MySQL会根据其插⼊适当的节点和位置，会导致移动数据，造成⼤量碎⽚
3：批量插⼊可以使SQL⽇志量（MySQL的binlog和innodb的事务让⽇志）减少了，降低⽇志刷盘的数据量和频率，从⽽提⾼效率。通过批量插⼊减少SQL语句解析的次数，减少⽹络传输的IO。
4：使⽤事务可以提⾼数据的插⼊效率，这是因为进⾏⼀个INSERT操作时，MySQL内部会建⽴⼀个事务，在事务内才进⾏真正插⼊处理操作。通过使⽤事务可以减少创建事务的消耗，所有插⼊都在执⾏后才进⾏提交操作。
5：多线程处理，这个就不要多说了。
