tera's Introduction

Build Status

Copyright 2015, Baidu.com, Inc.

#Overview Tera实现了按行key、列和时间戳全局排序的三维数据模型,并且针对万兆网卡和SSD进行了优化,适合海量记录(万亿量级)的持久存储和高效随机访问。

#特性 * 全局有序 * 热点自动分片 * 数据强一致 * 多版本,自动垃圾收集 * 按列存储,支持内存表 * 动态schema,支持稀疏表 * 表格快照 * 高效随机读写

#系统依赖 使用分布式文件系统(HDFS、NFS等)持久化数据与元信息

使用zookeeper选主与协调

使用Sofa-pbrpc实现跨进程通信

#API使用示例 参考sample.cc
