简史
Facebook
于
2008
年开源了
Hive
，它之后成了
Apache Hive
。在
Facebook
内部
Hive
被
广泛用于在巨大的
Apache Hadoop
集群上执行
HDFS
上的数据分析任务。
Facebook
的数据分析师使用
Hive
在大型数据仓库上执行交互式查询。在
Facebook
开发
出
Presto
之前，所有的分析师都依赖于

2012
年，
Facebook
的
Hive
数据仓库已经有
250PB
了，它每天需
要处理数百个用户的成千上万条查询。在
Facebook
内部，
Hive
逐渐到达极限，并且它
无法查询其他数据源。
Facebook
从零开始设计出了
Presto
，以便在其数据规模下快速地执行查询。
Presto
不是
创建一个新系统并将数据迁移过去，而是通过可插拔的连接器系统在数据存储的本地

Hive
连接器是
Presto
最早的连接器之一（参见
6.4

Hive
数据仓库中的数据。

名

工程师开始研发
Presto
，以满足
Facebook
在分析场景中对性能、
可扩展性和可伸缩性的需求。
Presto
最初就是要构建为开源项目。
2013
年年初，
Facebook
推出了
Presto
的初始版本。同年秋天，
Facebook
正式开源
Presto
。鉴于
Presto
在
Facebook
内部取得了成功，许多其他大型互联网公司也开始使用它，如
Netfl ix
、
