lealone's Introduction

Lealone是什么

  • 是一个兼具RDBMS、NoSQL优点的面向OLTP场景的异步化NewSQL单机与分布式关系数据库

Lealone有哪些特性

开源版本(不支持分布式事务)
  • 完全异步化,使用少量线程就能处理大量并发

  • 基于SQL优先级的抢占式调度,慢查询不会长期霸占CPU

  • 创建JDBC连接非常快速,占用资源少,不再需要JDBC连接池

  • 插件化存储引擎架构,内置AOSE引擎,支持单机与分布式存储

  • 插件化事务引擎架构,事务处理逻辑与存储分离,内置MVCC引擎,支持单机事务

  • 支持自动化分片(Sharding),用户不需要关心任何分片的规则,没有热点,能够进行范围查询

  • 支持索引、视图、Join、子查询、触发器、自定义函数、Order By、Group By、聚合

  • 支持混合运行模式,包括4种模式: 嵌入式、Client/Server模式、复制模式、Sharding模式

  • H2数据库借鉴了大量成熟的代码和**

企业版本
  • 支持分布式事务

  • 支持全局快照隔离

  • 支持强一致性复制

Lealone文档

Lealone名字的由来

  • Lealone 发音 ['li:ləʊn] 这是我新造的英文单词,
    灵感来自于办公桌上那些叫绿萝的室内植物,一直想做个项目以它命名。
    绿萝的拼音是lv luo,与Lealone英文发音有点相同,
    Lealone是lea + lone的组合,反过来念更有意思哦。:)
