An introduction to Apache Kylin Business Intelligence ...
summary
Apache Kylin is an eBay‑origin OLAP engine that builds key-value cubes with Hive pre-joins and MapReduce jobs, stores them in HBase/HDFS, and exposes a SQL interface via JDBC/ODBC. It targets billion+ rows and thousands of users, demonstrates fast, low‑latency queries by routing hot queries through HBase (seconds or better) while falling back to Hive for slower ones. Prototype shipped in months, it’s now an Apache incubator project with a GUI and roadmap items: Excel, Drill and Spark integration.
