### [Data Management for Data Science Towards Embedded Analytics](https://duckdb.org/pdf/CIDR2020-raasveldt-muehleisen-duckdb.pdf) | ||
|
||
> CIDR 2020 | ||
该论文探讨了数据科学领域对数据管理解决方案的需求,并提出了一类新的数据管理系统:嵌入式分析系统(embedded analytical systems)。 | ||
|
||
数据科学崛起导致数据分析任务复杂性增加,数据科学家通常使用脚本语言(如 Python 或 R)在个人电脑上进行中等规模的分析,传统的 RDBMS 不能满足数据科学家的需求,不适合本地数据分析用例。 | ||
|
||
嵌入式分析系统为了填补了这一空白,要解决如下一些问题: | ||
|
||
- Combined OLAP & ETL Workloads: 高效率地支持 OLAP 工作负载以及批量追加和更新 | ||
- Transfer Efficiency: 数据库和应用程序在同一进程和地址空间中运行,需要有效利用这一机会实现高效的数据共享 | ||
- Resilience: 嵌入式数据库需要能够检测硬件问题并防止数据损坏 | ||
- Cooperation: 系统需要能够适应资源竞争,与主机应用程序共享硬件资源 | ||
|
||
**DuckDB** | ||
|
||
DuckDB 是一个为嵌入式分析设计的新型关系型数据库管理系统。 | ||
|
||
- OLAP & ETL:使用矢量化解释执行引擎,优化了 OLAP 查询 | ||
- 弹性:DuckDB 计算并存储持久存储块的校验和,并在读取时验证,以保护数据完整性 | ||
- 协作:DuckDB 允许用户手动设置内存和 CPU 核心使用率的硬限制,并计划实现自适应资源使用方案 | ||
- 传输效率:DuckDB 实现了高效的客户端 API,允许客户端应用程序直接成为物理查询处理计划的根算子 | ||
