摘要
数据库是现代社会十分关键的基础设施,一直以来,数据库的扩展以纵向模式(Scale-up)为主,数据库系统的容量和性能更多依赖于服务器单机硬件(CPU/内存/磁盘/网络等)的提升,难以满足当今信息化社会对海量结构化数据的高性能、低成本的存储和处理能力的需求。本文设计和实现了一个基于横向扩展(Scale-out)模式的数据库系统OceanBase,该系统支持事务(ACID)和范围查询等关系数据库和SQL语言的主要功能分库分表不再需要,服务器可以在线地添加和移除。OceanBase已用于阿里巴巴的多个线上系统,每天提供数十亿次的实时读写访问服务。
DBMS is a critical infrastructure for modem society. Performance improvement of DBMS has relied on CPU/memory/storage/network updates in a dedicated site （scale-up） and thus makes DBMS feeble to handle today＇s massive structured data with high performance and low cost. In this paper, we have built OceanBase, a semi-distributed shared-nothing system which supports key features of RDBMS and SQL, e.g., general purpose transaction （ACID）, range query, etc. Sharding is obsolete and servers can be added/removed to/ from OceanBase on-the-fly. OceanBase has been used by dozens of projects in the product system of Alibaba and offers billions of real-time read and write queries every day.
