Apache Impala is the open source, native analytic database
for Apache Hadoop. Impala is shipped by Cloudera, MapR, Oracle, and Amazon.

 

Do BI-style Queries on Hadoop

Impala provides low latency低延迟 and high concurrency 高并发for BI/analytic queries on Hadoop (not delivered by batch frameworks such as Apache Hive). Impala also scales linearly, even in multitenant environments.

在Hadoop上执行BI风格的查询
Impala为Hadoop上的BI /分析查询提供了低延迟和高并发性(不是由Apache Hive等批处理框架提供的)。
即使在多租户环境中,Impala也能线性扩展。


Unify Your Infrastructure
Utilize the same file and data formats and metadata, security, and resource management frameworks as your Hadoop deployment—no redundant infrastructure or data conversion/duplication.

统一基础设施
与Hadoop部署一样,利用相同的文件和数据格式以及元数据,安全性和资源管理框架 - 无需冗余基础架构或数据转换/复制。


Implement Quickly

For Apache Hive users, Impala utilizes the same metadata and ODBC driver. Like Hive, Impala supports SQL, so you don‘t have to worry about re-inventing the implementation wheel.

快速实施
对于Apache Hive用户,Impala使用相同的元数据和ODBC驱动程序。与Hive一样,Impala支持SQL,因此您不必担心重新实现轮子。


Count on Enterprise-class Security

Impala is integrated with native Hadoop security and Kerberos for authentication, and via the Sentry module, you can ensure that the right users and applications are authorized for the right data.

依靠企业级安全
Impala与本地Hadoop安全和Kerberos进行身份验证集成,并且通过Sentry模块,您可以确保正确的用户和应用程序获得正确数据的授权。



Retain Freedom from Lock-in

Impala is open source (Apache License).

保持自由锁定
Impala是开源的(Apache许可证)。

Expand the Hadoop User-verse
With Impala, more users, whether using SQL queries or BI applications, can interact with more data through a single repository and metadata store from source through analysis.

展开Hadoop User-verse
通过Impala,无论使用SQL查询还是BI应用程序,更多用户都可以通过单个存储库和元数据存储从源代码通过分析与更多数据进行交互。
