Impala和hBASE之间的区别

1.黑斑羚：
Impala是在Hadoop上运行的查询引擎。它对存储在Hadoop中的数据提供高性能，低延迟的SQL查询。它是一个开源软件。它支持内存中的数据处理。它开创了Parquet文件格式的使用，Parquet文件格式是一种列式存储布局，已针对数据仓库场景中典型的大规模查询进行了优化。

2. HBase：
该模型用于提供对大量结构化数据的随机访问。它建立在hadoop文件系统的顶部，本质上是面向列的。它曾用于将数据存储在HDFS中。它是提供数据复制的开源数据库。

Impala和hBASE之间的区别：

S.NO.	Impala	HBase
1.	It was developed by Cloudera.	Developed by Apache software foundation.
2.	Impala was released in 2013	HBase was released in 2008
3.	Impala is implemented using c++ programming language	HBase is implemented using  JAVA programming language
4.	Linux is the only server operating system using Impala.	Linux, Unix and Windows are server operating system using HBase.
5.	It supports SQL such as DML and DDL statements.	It does not support SQL(standard query language).
6.	Triggers are not used in Impala	Triggers are used in HBase
7.	JDBC and ODBC are the APIs and access methods used in Impala.	Java API, RESTful HTTP API, Thrift are the APIs and access methods used in Impala.
8.	Replication methods used in Impala are selectable replication factor.	Replication methods used in HBase are Master-master replication, Master-slave replication.
