1.Hive：
Hive是一种数据仓库软件，用于查询和管理基于 Hadoop 的大型分布式数据集。它由 Apache Software Foundation 于 2012 年开发。它包含两个模块，一个是 MapReduce，另一个是 Hadoop 分布式文件系统 (HDFS)。它将模式存储在数据库中并将处理后的数据存储到 HDFS。它驻留在 Hadoop 之上以汇总大数据，并使查询和分析变得容易。
2. 卡桑德拉：
Cassandra 是一个免费、开源、分布式、广泛的列存储、NoSQL 数据库管理系统。它由 Apache 软件基金会开发，最初于 2008 年 7 月发布。Cassandra 旨在处理跨多个商用服务器的大量数据，提供高可用性且无单点故障。
