FOREST HILL, Md., April 1, 2014 /PRNewswire-USNewswire/ -- The Apache Software
Foundation (ASF), the all-volunteer developers, stewards, and incubators of
more than 170 Open Source projects and initiatives, announced today that
Apache Tajo has graduated from the Apache Incubator to become a Top-Level
Project (TLP), signifying that the project's community and products have been
well-governed under the ASF's meritocratic process and principles.

"It's a pleasure to graduate from the Apache Incubator," said Hyunsik Choi,
Vice President of Apache Tajo. "This milestone further reinforces our hard
work in bringing a much-needed big data solution under the Apache banner."

Dubbed an "SQL-on-Hadoop" solution, Apache Tajo is a robust big data
relational and distributed data warehouse system for Apache Hadoop. Tajo is
designed for low-latency and scalable ad-hoc queries, online aggregation, and
ETL (extract-transform-load process) on large-data sets stored on HDFS (Hadoop
Distributed File System) and other data sources. By supporting SQL standards
and leveraging advanced database techniques, Tajo allows direct control of
distributed execution and data flow across a variety of query evaluation
strategies and optimization opportunities.

The Tajo project began in 2010 at Korea University's Database Lab, and entered
the Apache Incubator in March 2013. Apache Tajo is in use at Gruter, Korea
University, and SK Telecom, among others, for its ability to analyze massive
data sets in real time.

"Apache Tajo has earned its place as a top-level project in the ASF. It's an
excellent example of a community building around a core piece of technology.
Not to mention, the technology itself is quite cool. Tajo has a large role to
play in the Apache Hadoop ecosystem," said Jakob Homan, Staff Software
Engineer at LinkedIn, and ASF Member.

"Tajo project is a really good example that how company and Open Source
community can benefit from each other. Its real open community has assisted me
to solve lots of practical problems, and I have opportunities to make Tajo
more robust and have richer functionalities," said Keuntae Park, IT manager of
SK Telecom and contributor to Apache Tajo. "I feel much affection for Tajo
project and it's my great pleasure to participate in its growth, graduation,
and becoming of top-level project."

"Tajo is one of the most promising projects for SQL-on-Hadoop. Many
contributors have been improving Tajo by developing various interesting
features. It's an honor for me to work with such a wonderful community," said
Jihoon Son, Ph.D. candidate at Korea University and contributor to Apache

"Apache Tajo has been a model community through the Incubator. They have
demonstrated meritocracy on lists in the face of some pretty awesome and
complex software for Big Data Analytics," said Chris Mattmann, Apache Tajo
Incubator Mentor at the ASF, and Chief Architect, Instrument and Science Data
Systems Section at NASA JPL. "We are currently evaluating the use of Tajo in
projects for Radio Astronomy at JPL, as well as in the context of our Airborne
Snow Observatory (ASO) project for Big Data query processing and storage. I'm
really excited to see where Tajo is headed along with the other Big Data
stacks at the ASF including Spark and Mesos."

"The key to a successful Open Source community lies in its diversity and
active participation," added Choi. "As Apache Tajo continues to grow, we
welcome contributions with code, documentation, testing, submitting patches,
and other valuable forms of feedback."

Availability and Oversight
As with all Apache products, Apache Tajo 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.
