Apache Kylin: Speed Up Cubing with Apache Spark

Download Slides

Apache Kylin is a distributed OLAP engine on Hadoop, which provides sub-second level query latency over datasets scaling to petabytes. Kylin’s superior query performance relies on pre-calculated multi-dimension Cube, which is often time-consuming to build. By default, Kylin uses MapReduce Cube Engine built atop of Hadoop MapReduce framework to aggregate huge amounts of source data. The MR Engine has been well-tuned over years and proven to be stable in hundreds of production deployments. Recently, the Kylin team is trying to further speed up the process of cube building by replacing MR with Spark. Kyligence has initiated the new Spark Cube Engine with some benchmarks between Spark and MR over different datasets, and has received some promising results. Hear about their results and experiences on moving Cube building, which is a huge computing task, to Spark.
