问题描述

MaxMind GeoIP2数据库的二进制文件系统的大小是多少?我要问的是国家和城市级别的数据库.

What's the size on file system of the MaxMind GeoIP2 databases in binary format? I'm asking about both the country and the city level db.

很遗憾，我在任何地方都找不到此信息.

Unfortunately I can't find this information anywhere.

我知道文件大小会随着时间而变化，但是我需要粗略估计存储需求.

I know the file size will change over time but I need to roughly estimate the storage requirements.

还有，有人知道解析单个IP的最小控制台应用程序上的内存占用吗?

Also, does anybody know the memory footprint on a minimal console application that resolve a single ip?

推荐答案

当前的City数据库约为122 MB.内存占用量将取决于您用于读取文件的特定API.大多数官方API都会对文件进行内存映射，因此无需将整个数据库加载到实际内存中.

The current City database is approximately 122 MB. The memory footprint would depend on the particular API you are using to read the file. Most of the official APIs memory-map the file so there is no need to load the whole database into real memory.
