Apache Impala

Apache Impala (incubating) is the open source, native analytic database for Apache Hadoop.

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

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.

Implement Quickly
---------------------------------------
For Apache Hive users, Impala utilizes the same metadata, ODBC driver, SQL syntax, and user interface as Hive—so you don't have to worry about re-inventing the implementation wheel.

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.

Retain Freedom from Lock-in
---------------------------------------
Impala is open source (Apache License).

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.
