Perl DBM与可存储 [英] Perl DBM vs. Storable

问题描述

对于我当前的项目，我需要在磁盘上存储一个小数据库，程序运行后我将读取该数据库，并将其写入一次.

for my current project i need to store a little database on disk, that i read once my program runs and write it once.

我研究了perls DBM功能，据我了解，它仅提供存储在磁盘上的哈希值，而每次读取和写入操作都直接进入磁盘.

I have looked into perls DBM functionality and from what I understand it provides merely a hash that is stored on disk with every read and write going directly to disk.

我的问题是:我不能简单地使用Storable或任何相关模块来以更少的文件I/O开销实现相同的(持久性哈希)吗? (散列永远不会太大，以至于无法轻松地放入内存中)

My question is: Could I not simply use Storable or any of the related modules to achieve the same (a persistent hash) with far less File I/O overhead? (The hashes will never be to large to fit into memory easily)

推荐答案

SQLite 迅速成为简单在线操作的标准-磁盘数据库.在Perl中，您只需使用 DBD :: SQLite ，您就可以开始使用了.

SQLite is fast becoming the standard for simple on-disk databases. And in Perl you can just use DBD::SQLite and you're good to go.
