google的levelDB是我很感兴趣并且通读源码的开源项目,因此记录一下源码的阅读过程
levelDB的安装,参考:http://blog.csdn.net/koko2015c/article/details/68066761 ,其实也就是make一下,把动态链接库和API复制到本地,说是一个数据库,实际上说levelDB是库更贴切。
github地址: https://github.com/google/leveldb
使用说明: https://github.com/google/leveldb/blob/master/doc/index.md
测试程序
#include "leveldb/db.h" #include <cassert> #include <iostream> using namespace std; using namespace leveldb; int main() { leveldb::DB *db; leveldb::Options options; options.create_if_missing = true; leveldb::Status status = leveldb::DB::Open(options, "testdb", &db); assert(status.ok()); status = db->Put(WriteOptions(), "abc", "levelDB here!"); assert(status.ok()); string res; status = db->Get(ReadOptions(), "abc", &res); assert(status.ok()); cout << res << endl; delete db; return 0; }
