Features

  • 完全基于磁盘,不受内存限制
  • KV、List、Map、Zet、ZSET等丰富的数据结构
  • 最高百万级别的查询性能和十万级的写入性能
  • 原子性写入,读写无冲突
  • TTL(生存时间)
  • 备份与恢复
  • ACID事物
  • 多节点一致性支持(官方插件使用Raft协议支持强一致性,也可自行使用其他协议或方式)

KitDB和Redis的性能对比

注意:KitDB的测试为本地操作,和Redis对比无意义,只为说明KitDB的性能级别

Requirements

编译要求:JDK 8+和Maven 3.2.5+

单元测试默认数据存储路径为/data/kitdb 如需调整,可用-Dkitdb_path 指定,例如:

test -Dkitdb_path=D:\\temp\\db -f pom.xml

Explain

store模块为KitDB本体,raft模块为官方Raft协议插件

操作系统兼容问题

对常用进行开发和运行环境的操作系统进行测试,操作系统使用官方镜像重新安装,排除干扰。开发环境IDE使用IntelliJ IDEA Community。
