  4. 4. Why Happiness Latency 10s
  5. 5. What we have tried? Kylin
  6. 6. About Apache Kylin http://kylin.apache.org Extreme OLAP Engine for Big Data Apache Kylin is an open source Distributed Analytics Engine designed to provide SQL interface and multi-dimensional analysis (OLAP) on Hadoop, supporting extremely large datasets and sub-second level response time. kylin / ˈkiːˈlɪn / 麒麟 --n. (in Chinese art) a mythical animal of composite form
  7. 7. About Apache Kylin OLAP/数据集市 • Born for Big Data Anlytics • Sub-seconds Latency • ANSI SQL • Seamless Integration with BI Tools • Plug-able Architecture

  16. 16. The Evolution
  17. 17. Apache Kylin New Features § Plugin-able architecture § New MR Cube Engine with fast cubing (1.5x faster) § New HBase Storage with parallel scan (2x faster) § Near real-time analysis § User defined aggregations § Excel / PowerBI / Zeppelin integration
  18. 18. The Freedom, Extensibility, Flexibility § Freedom § Zoo break, not bound to Hadoop any more § Free to go to a better engine or storage § Extensibility § Accept any input, e.g. Kafka § Embrace next-gen distributed platform, e.g. Spark § Flexibility § Choose different engine for different data set
  19. 19. New generation design Cube Builder (MapReduce…) SQL Low Latency - SecondsRouting 3rd Party App (Web App, Mobile…) Metadata SQL-Based Tool (BI Tools: Tableau…) Query Engine Hadoop Hive REST API JDBC/ODBC Ø Online Analysis Data Flow Ø Offline Data Flow Ø Clients/Users interactive with Kylin via SQL Ø OLAP Cube is transparent to users Star Schema Data Key Value Data Data Cube OLAP Cubes (HBase) SQL REST ServerData Source Abstraction Engine Abstraction Storage Abstraction

  22. 22. Parallel Scan § Slow queries are 5-10x faster. § New Hbase storage enables partition on cuboids that are big enough. § Overall query time is 2x faster than before, sum results from 10,000+ queries.
