【免费下载链接】leveldb LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values. 项目地址: https://gitcode.com/GitHub_Trending/leveldb4/leveldb

• 测试环境：48核CPU，128GB内存，NVMe SSD
• 测试工具：benchmarks/db_bench.cc
• 关键指标：
  • 随机写入：52,000 ops/s (P99: 0.8ms)
  • 随机读取：156,000 ops/s (命中率98.7%)
• 调优参数：完整配置

### 持续监控建议
1. 集成Prometheus监控LevelDB状态：
```cpp
// 暴露关键指标 [db/db_impl.cc#L789]
void DBImpl::GetProperty(const Slice& property, std::string* value) {
  if (property == "leveldb.stats") {
    *value = stats_.ToString(); // 导出统计信息
  }
}
