介绍

resob是remote service of BsTr tree的缩写。包resob定义了一个名为BsTr的结构，并基于该结构实现了一个可以指针混写的类B+树，借鉴脉动工作流模式，支持表级并行度。纯go标准库实现，没有额外的依赖。
resob_jsondb是基于BsTr树的json数据库，支持特定的json格式作为包含数据的操作命令，通过解析json实现插入、删除、更新和查找。

特性

具有在go结构体和BsTr struct之间实施相互转换的能力；具备在BsTr struct和json字符串之间实施序列化和反序列化的能力。
具备基于BsTr struct简捷生成BsTr tree（blink tree）的能力；BsTr tree可以在内存块和磁盘page间实施指针混写。
BsTr tree支持5种key（[]byte、string、int64,、float64、complex128）任意value的插入、删除、更新和查找（具备服务端分页能力），可以分为单线程和多线程模式工作，具备表级并行。
BsTr tree支持UNIQUE、COMPRESS、FILE、BIG、FILEBIG、NOSERIAL等key标识。
resob_jsondt基于BsTr tree，实现了两种key类型(string、int64)value为json数据的插入、删除、更新和查找（具备服务端分页能力），json的字段会被分别存储并建立索引。
resob_jsondb是基于resob_jsondt实现的json解析数据库，可以很容易地实现为提供远程json解析数据存储或缓存服务。resob-http-simpleadmin是基于resobdb的一个demo实现，包含服务端及管理界面，所有的操作采用json格式的命令，通过http发送和接收数据。
