求解
你的需求这样是解决不了的

要分开处理。。。。。

比如，可将ip按第一位，写到255个文件里面，，，也可以将ip转换成数字，这样处理后续可以少用点内存

分别在255个文件里面，找出前1000名。。。因为每组至多包含2^24个不同的数【暂时不考虑ipv6】，这个内存可接受的
这样用一个数组遍历，复杂度O(n)，即可找出前1000

最后维护一个1000的有序数组，往里面插入数据即可，超过1000，弹出最小的那个 
=====
能给出例子代码吗?

------解决方案--------------------
一次读取100W条数据，内存肯定吃不消，再来几个并发，那就更不得了了，还是分段读取，按2楼说的那样，把内容放到N个文件中，读取频率最高的，这样不至于一次打开一个上T的文件
