Apache Kylin is an open source distributed analytics engine designed to provide a SQL interface and multi-dimensional analysis (OLAP) on Hadoop and Alluxio supporting extremely large datasets.

It was originally developed by eBay, and is now a project of the Apache Software Foundation.[3]

History

The Kylin project was started in 2013, in eBay's R&D in Shanghai, China. In Oct 2014, Kylin v0.6 was open sourced on github.com with the name "KylinOLAP".[4]

In November 2014, Kylin joined Apache Software Foundation incubator.

In December 2015, Apache Kylin graduated to be a Top Level Project.[3]

In March 2016, Kyligence, Inc. was founded by the creators of Apache Kylin.[5][6] Kyligence provides a commercial analytics platform based on Apache Kylin for on-premise and cloud-based datasets.[7]

Architecture

Apache Kylin is built on top of Apache Hadoop, Apache Hive, Apache HBase, Apache Parquet, Apache Calcite, Apache Spark and other technologies.[8] These technologies enable Kylin to easily scale to support massive data loads.[9]

Kylin has the following core components:[10][8]

Users

Apache Kylin has been adopted by many companies as their OLAP platform in production. Typical users includes eBay, Meituan, XiaoMi, NetEase, Beike, Yahoo! Japan.
