The Apache Kylin team is pleased to announce the immediate availability of

Distributed query engine), with 42 bug fixes and enhancements.

Apache Kylin is an open-source Distributed Analytical Data Warehouse for

Big Data; it was designed to provide OLAP (Online Analytical Processing)

capability in the big data era. By renovating the multi-dimensional cube

and precalculation technology on Hadoop and Spark, Kylin is able to achieve

near-constant query speed regardless of the ever-growing data volume.

Reducing query latency from minutes to sub-second, Kylin brings online

analytics back to big data.




Apache Kylin lets you query billions of rows at sub-second latency in 3

steps:

1. Identify a Star/Snowflake Schema on Hadoop.

2. Build Cube from the identified tables.

3. Query using ANSI-SQL and get results in sub-second, via ODBC, JDBC or

RESTful API.




Thanks to everyone who has contributed to this release.
