Open Source columnar storage engine for the Apache Hadoop ecosystem in use at 
Xiaomi, JD Mall, and RMS, among others. 

Forest Hill, MD —20 September 2016— The Apache Software Foundation (ASF), the 
all-volunteer developers, stewards, and incubators of more than 350 Open Source 
projects and initiatives, announced today the availability of Apache® Kudu™ 
v1.0, the Open Source columnar storage engine built for the Apache Hadoop® 

Apache Kudu is designed to enable flexible, high-performance analytic 
pipelines.Optimized for lightning-fast scans, Kudu is particularly well suited 
to hosting time-series data and various types of operational data. In addition 
to its impressive scan speed, Kudu supports many operations available in 
traditional databases, including real-time insert, update, and delete 
operations. Kudu enables a "bring your own SQL" philosophy, and supports being 
accessed by multiple different query engines including such other Apache 
projects as Drill™, Spark™, and Impala (incubating). 

"The Apache Kudu 1.0 release represents a major milestone for the project," 
said Todd Lipcon, Vice President of Apache Kudu. "One year after the first 
public beta, the community is confident that Kudu is ready for production for 
critical business use cases." 

Apache Kudu 1.0 is the project's first milestone release since first joining 
The Apache Software Foundation a year ago, and includes a number of important 
features that include: 

- Support for redundant and highly available Kudu Master nodes; 
- Support for manual management of range partitioning, critical for time series 
- Rewritten integration with Apache Spark, including Spark SQL and Data Frame 
- An officially supported client library for Python; and 
- Substantial performance improvements both for random access and analytic 

These features, along with hundreds of other improvements, bug fixes, and 
optimizations, represent the work of more than 40 contributors in the Apache 

Apache Kudu is in use at numerous organizations around the world, spanning 
industries such as retail, online service delivery, risk management, and 
digital advertising. Early users of Kudu include Xiaomi (the world's fourth 
largest smart-phone maker), JD Mall (China's largest B2C online retailer), and 
RMS (the market leader in catastrophe risk modelling).

After three years of prototyping and development, Kudu was first unveiled to 
the world at Strata/Hadoop World NYC in September, 2015. Several months later, 
Kudu was submitted to the Apache Incubator, where the project began to attract 
a community of active developers and users. In July, 2016, Kudu graduated as an 
Apache Top-Level Project. 

"Kudu 1.0 is the most performant, full-featured, and stable release of Kudu 
yet. Every day we see new users joining the community, deploying Kudu alongside 
other Apache projects such as Impala and Spark to solve valuable real-time use 
cases," added Lipcon. "Kudu expands the Apache Hadoop ecosystem's capabilities, 
enabling real-time data ingestion and updates while also serving high 
performance analytics with a substantially simplified architecture." 

The Apache Kudu project welcomes contributions and community participation 
through mailing lists, a Slack channel, face-to-face MeetUps, and other events. 
Catch Apache Kudu in action at Strata/Hadoop World, 26-29 September in New York 
City, where engineers from Cloudera, Comcast Xfinity, and GE Digital will 
present sessions related to Kudu.

Availability and Oversight 
Apache Kudu software is released under the Apache License v2.0 and is overseen 
by a self-selected team of active contributors to the project. A Project 
Management Committee (PMC) guides the Project's day-to-day operations, 
including community development and product releases. For downloads,
