-threaded algorithm, but Kylin uses a parallel algorithm.User-TOPN queries, such as fetching 100 data, are written as SQL statements as shown in. and Kylin will automatically adapt to such a SQL to directly use the pre-aggregated good results, so at run time Kylin just put the pre-calculated 1000, 10,000 item directly back to the good, there is almost no online calculation, the speed will be very fast. 7. Integration of analysis tools In the new version, Kylin also added some ODBC interfaces,

online memory-based high-speed analysis. Transwarp Data Hub integrates Data integration/ETL, big Data storage and online service systems, memory-based efficient computing engines, high-performance SQL, statistical analysis, and machine learning, achieving Performance breakthroughs. In Sun yuanhao's words, Transwarp Data Hub has a "lightning" speed, which is 10-10 faster than the open-source Hadoop 2.0 ~ 100 times. In addition, Transwarp Data Hub has powerful analysis capabilities and is fully c
