mdrill's Introduction

项目简介

1:mdrill是阿里妈妈-adhoc-海量数据多维自助即席查询平台下的一个子项目。
2:mdrill旨在帮助用户在几秒到几十秒的时间内,分析百亿级别的任意维度组合的数据。
3:mdrill是一个分布式的在线分析查询系统,基于hadoop,lucene,solr,jstorm等开源系统作为实现,基于SQL的查询语法。 mdrill是一个能够对大量数据进行分布式处理的软件框架。mdrill是快速的高性能的,他的底层因使用了索引、列式存储、以及内存cache等技术,使得数据扫描的速度大为增加。mdrill是分布式的,它以并行的方式工作,通过并行处理加快处理速度。
4:基于mdrill应用的adhoc项目,使用了10台机器,存储了400亿的数据,每次扫描30亿的行数,响应时间在20秒~120秒左右(取决不同的查询条件)。
